Abstract We report results from sequential extraction experiments and the quantitative mineralogy

for samples of stream sediments and mine wastes collected from metal mines Samples were from the Elizabeth Ely Copper and Pike Hill Copper mines in Vermont the Callahan Mine in Maine and the Martha Mine in New Zealand The extraction technique targeted the following operationally defined fractions and solid-phase forms (1) soluble adsorbed and exchangeable fractions (2) carbonates (3) organic material (4) amorphous iron- and aluminum-hydroxides and crystalline manganese-oxides (5) crystalline iron-oxides (6) sulfides and selenides and (7) residual material For most elements the sum of an element from all extractions steps correlated well with the original unleached concentration Also the quantitative mineralogy of the original material compared to that of the residues from two extraction steps gave insight into the effectiveness of reagents at dissolving targeted phases The data are presented here with minimal interpretation or discussion and further analyses and interpretation will be presented elsewhere

Introduction Sequential partial dissolutions were used to characterize the distribution of elements in

stream sediments mine wastes and flotation-mill tailings from several metal mines The procedure was developed to extract metals associated with operationally defined solid phases to provide insight into speciation and possible bioavailability This study was prompted by concerns about the potential environmental impact of elevated selenium concentrations in stream sediments raised by the preliminary Baseline Ecological Risk Assessment (BERA) at the Elizabeth Mine in Vermont Additional samples from elsewhere in the Vermont copper belt and beyond were selected for comparison purposes The distribution of selenium in extraction fractions and implications with respect to potential bioavailability were discussed by Piatak and others (2006a 2006b) This report presents the results of the major and trace elements in unleached samples and in extracts and residues from the dissolutions Also quantitative mineralogy of the original samples and several residues was included

Samples were collected from the Elizabeth (fig 1) Ely Copper (fig 2) and Pike Hill Copper (fig 3) mines all Superfund sites in the Vermont copper belt and include stream sediments oxidized mine waste and flotation-mill tailings (table 1) These deposits mined primarily for copper and zinc are Besshi-type massive sulfide deposits composed of pyrrhotite

chalcopyrite and minor sphalerite and pyrite (Slack and others 2001) Fine-grained flotation-mill tailings from the Callahan Mine a Superfund site in Brooksville Me were also collected (table 1 and fig 4) This mine exploited a Kuroko-type massive sulfide deposit that contained bodies of pyrite sphalerite and chalcopyrite that were mined for zinc copper lead and gold (Bouley and Hodder 1984) Flotation-mill tailings were also examined from the Martha Mine in Waihi New Zealand which is an epithermal gold-silver deposit (Castendyk and others 2005) (table 1)

Methods

Mineralogy

Minerals were identified by powder X-ray diffraction analysis (XRD) Diffraction patterns were collected using a Scintag X1 automated powder diffractometer equipped with a Peltier detector with CuKα radiation The XRD patterns were analyzed using Material Data Incrsquos JADE software and standard reference patterns Relative amounts of phases were estimated using the Siroquant computer program which utilizes the full XRD profile in a Rietveld refinement (Taylor and Clapp 1992) The analytical uncertainty of the Siroquant results is approximately plusmn 5 wt The colors of the samples given in table 1 were determined using soil color charts (Munsell Soil Color Charts 1994)

Sequential Extractions

Seven-step sequential extractions were done on nineteen mine-waste and stream-sediment samples on three duplicates and on two blanks (table 1) One blank was used for analytical calibration purposes (Extract ID lsquoArsquo in table 1) Samples were either grab or composites Most composites consisted of a minimum of 30 sample increments sampled over a measured area divided into a stratified grid One stream-sediment composite (Ely-SD-09) consisted of three increments from different depositional areas in the stream Samples were air-dried sieved to lt2 mm (or lt180 μm for sample 1139830-SD stream sediment from Pike Hill) and homogenized (table 1) After digestion by a mixture of HCl-HNO3-HClO4-HF a split of the original untreated sample was analyzed by inductively coupled plasma-mass spectrometry (ICPshyMS) to determine the major- and trace-element composition (Briggs and Meier 2002) A split of the original untreated sample was also analyzed by hydride-generation atomic absorption spectrometry (HG-AAS) to determine the concentration of Se after the sample was digested with a mixture of HNO3-HF-HClO4 (Hageman and others 2002) Residues remaining after extraction steps 5 and 6 were analyzed after digestion by ICP-MS and HG-AAS Extraction solutes were analyzed by ICP-MS (Lamothe and others 2002) The analyses were done in US Geological Survey (USGS) laboratories in Denver Colo The accuracy of both methods was approximately plusmn10

The distribution of elements determined by sequential extractions were operationally defined by the reagents used the reaction times temperatures and solid-to-extraction solution ratio for each step No single reagent time and temperature combination could be applied to all sample types to recover a given phase extractions were matrix-dependent This extraction procedure also attempted to differentiate the amorphous (step 4) versus crystalline (step 5) iron-oxide and iron-hydroxide phases There is a gradation from amorphous to cryptocrystalline to crystalline iron-oxides and hydroxides Hall and others (1996a) discussed the subtleties in differentiating among the phases depending on reagent strength Additional complicating factors included the possibility that occluded grains might persist past their designated dissolution step or factors such as grain size mineralogy or solid solution may affect the reactivity of phases The sequential extraction procedure used in this study is outlined below and illustrated in figure 5 The procedure was a combination of methods developed by Chao (1972) Chao and Sanzolone (1977 1989) Chao and Zhou (1983) Chester and Hughes (1967) Hall and others (1996a b) and Kulp and Pratt (2004) The hypothetically targeted species in each step are given in italics

bull Step 7 (residual material) Dry residue at approximately 100degF (~38degC) Digest sample with mixture of concentrated acids and analyze by ICP-MS and HG-AAS (Residue 6)

Results

Mineralogy

The quantitative mineralogy of the original unleached samples and residues after extraction steps 5 (residue 5) and 6 (residue 6) are given in Appendix 1 The relative amounts of phases in each sample in weight percent (wt ) were for the crystalline part of the sample only The percentages of phases in the residues were normalized with respect to weight loss due to the dissolution of the various phases during the previous extraction steps This measured weight loss in weight percent is given in Appendix 1 The detection limit for XRD was on the order of a few weight percent and therefore phases present in trace amounts were likely below reliable detection

Most samples primarily were composed of silicates including quartz feldspar (albite anorthite labradorite microcline orthoclase) hornblende mica (muscovite) chlorite and clay (kaolin vermiculite and vermiculite-type mixed layer clay) The mineralogy of the residues suggested that most of these silicates were resistant to the extraction reagents The exceptions were several clay minerals such as vermiculite and the vermiculite-type mixed layer clay and in some cases hornblende The vermiculite-type mixed layer clay had an intense broad peak at a spacing of approximately 115 to 120 Aring which was assigned to sepiolite by the XRD phase matching software Sepiolite commonly forms in shallow seas and lakes and is not likely to be found in mine waste so this peak was likely from a hydrous altered biotite (Poppe and others 2001) According to Rebertus and others (1986) biotite weathers to interstratified biotiteshyvermiculite (hydrobiotite) thus this low angle peak may have been the result of varying degrees of biotite alteration

The only sample that contained significant carbonate was the tailings from the Callahan Mine (CLHN-TP-2) having nearly 20 wt calcite The second step using acetic acid aimed at dissolving carbonate minerals such as calcite [CaCO3] and dolomite [CaMg(CO3)2] (Kulp and Pratt 2004) The residue remaining after step 5 did not contain detectable calcite dissolution of calcite had taken place between steps 1 and 5

Step 4 of the extraction procedure targeted amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides (Chao 1972 Chao and Zhou 1983 Hall and others 1996a) No crystalline manganese-oxide phases were detected by XRD The crystalline Fe-oxide and Fe-hydroxysulfate minerals found in these samples included goethite [FeOOH] hematite [Fe2O3] and jarosite [K2Fe6(SO4)4(OH)12] Chester and Hughes (1967) reported the dissolution of crystalline iron-oxide minerals (goethite and hematite) using the reagents in step 5 Only partial dissolution of jarosite was expected based on a study by Filipek and Theobald (1981) Based on the mineralogy of residue 5 the reagents in steps 1 through 5 did not generally digest hematite and only partially digested goethite and jarosite (Appendix 1)

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

Sequential Extractions

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

The sum of the concentrations of an element leached from the solids in steps 1 through 5 plus the residue after step 5 (calculated total) should be equal to the original total element concentration of the solid (bulk total) The calculated total from the extractions generally correlated with the original unleached concentration for most of the major elements Figure 6 shows these correlations for iron and calcium with the bulk total shown on the x-axis and the calculated total shown on the y-axis As shown many values plot within the plusmn 10 analytical uncertainty associated with the ICP-MS The stream sediment from the Pike Hill Copper Mine is anomalous in figure 6 For calcium the sum of extractions 1 through 5 plus residue 5 falls within an acceptable range but for nearly all samples the concentration in residue 6 was higher than in the original sample (not shown) Therefore the data for residue 6 for calcium were considered invalid and extract steps 6 and 7 were grouped together (sulfideselenide and residual fractions) This was also applied to magnesium and manganese because a significant amount of samples contained higher concentrations of these elements in the final residue (residue 6) compared to the unleached sample A reagent that contained sodium was used in step 3 so concentrations in extracts after this step were not examined The concentrations of sodium in extracts 1 and 2 were at or below the detection limit for all samples except the tailings from the Martha Mine Most aluminum was higher in the summed concentrations compared to the bulk

concentration and for nearly all the samples the concentration in residue 6 was higher than in the original This suggests one of the reagents may have been contaminated with aluminum

Figure 6 Calculated iron (Fe) and calcium (Ca) totals from extractions versus total from untreated samples Calculated totals are the sum of an element in extracts 1 2 3 4 and 5 and in the residue after step 5 Zero was used for concentrations less than the detection limit The black line represents a 11 correlation and the red dashed lines represent the analytical uncertainty of plusmn 10

The calculated totals for trace elements generally correlated with concentrations in the unleached sample In figure 7 the concentrations of arsenic copper selenium and zinc for most samples fall within the plusmn 10 ICP-MS and HG-AAS analytical uncertainties As with iron and calcium the Pike Hill stream sediment is anomalous for copper and zinc The results of the sequential extraction on other trace elements such as cadmium cobalt lead and nickel also were reasonable because calculated totals generally correlated with the original bulk concentrations Based on these comparisons the validity of the data from the extractions was assessed For most elements the extraction results were within the acceptable range of error Future reports will interpret the results of the sequential extractions in more detail

Methods

Mineralogy

Minerals were identified by powder X-ray diffraction analysis (XRD) Diffraction patterns were collected using a Scintag X1 automated powder diffractometer equipped with a Peltier detector with CuKα radiation The XRD patterns were analyzed using Material Data Incrsquos JADE software and standard reference patterns Relative amounts of phases were estimated using the Siroquant computer program which utilizes the full XRD profile in a Rietveld refinement (Taylor and Clapp 1992) The analytical uncertainty of the Siroquant results is approximately plusmn 5 wt The colors of the samples given in table 1 were determined using soil color charts (Munsell Soil Color Charts 1994)

Sequential Extractions

Seven-step sequential extractions were done on nineteen mine-waste and stream-sediment samples on three duplicates and on two blanks (table 1) One blank was used for analytical calibration purposes (Extract ID lsquoArsquo in table 1) Samples were either grab or composites Most composites consisted of a minimum of 30 sample increments sampled over a measured area divided into a stratified grid One stream-sediment composite (Ely-SD-09) consisted of three increments from different depositional areas in the stream Samples were air-dried sieved to lt2 mm (or lt180 μm for sample 1139830-SD stream sediment from Pike Hill) and homogenized (table 1) After digestion by a mixture of HCl-HNO3-HClO4-HF a split of the original untreated sample was analyzed by inductively coupled plasma-mass spectrometry (ICPshyMS) to determine the major- and trace-element composition (Briggs and Meier 2002) A split of the original untreated sample was also analyzed by hydride-generation atomic absorption spectrometry (HG-AAS) to determine the concentration of Se after the sample was digested with a mixture of HNO3-HF-HClO4 (Hageman and others 2002) Residues remaining after extraction steps 5 and 6 were analyzed after digestion by ICP-MS and HG-AAS Extraction solutes were analyzed by ICP-MS (Lamothe and others 2002) The analyses were done in US Geological Survey (USGS) laboratories in Denver Colo The accuracy of both methods was approximately plusmn10

The distribution of elements determined by sequential extractions were operationally defined by the reagents used the reaction times temperatures and solid-to-extraction solution ratio for each step No single reagent time and temperature combination could be applied to all sample types to recover a given phase extractions were matrix-dependent This extraction procedure also attempted to differentiate the amorphous (step 4) versus crystalline (step 5) iron-oxide and iron-hydroxide phases There is a gradation from amorphous to cryptocrystalline to crystalline iron-oxides and hydroxides Hall and others (1996a) discussed the subtleties in differentiating among the phases depending on reagent strength Additional complicating factors included the possibility that occluded grains might persist past their designated dissolution step or factors such as grain size mineralogy or solid solution may affect the reactivity of phases The sequential extraction procedure used in this study is outlined below and illustrated in figure 5 The procedure was a combination of methods developed by Chao (1972) Chao and Sanzolone (1977 1989) Chao and Zhou (1983) Chester and Hughes (1967) Hall and others (1996a b) and Kulp and Pratt (2004) The hypothetically targeted species in each step are given in italics

bull Step 1 (soluble adsorbed and exchangeable fraction) Combine 10 g of sample with 25 mL 01 M KH2PO4 agitate for 2 hours at 25ordmC Centrifuge for 10 minutes (15000 rpm Sorvall RC2-B refrigerated supercentrifuge) decant extract and dilute with deionized water (DIW) to 50 mL Add 500 microL concentrated ultrapure HNO3 Analyze extract by ICP-MS (Extract 1)

bull Step 2 (carbonates) Combine residue with 25 mL 15 acetic acid agitate for 2 hours centrifuge decant fill to 50 mL volume with DIW Analyze extract by ICP-MS (Extract 2)

bull Step 3 (organic material) Combine residue with 25 mL 01 M sodium pyrophosphate and agitate for 1 hour Centrifuge and decant Add another 25 mL 01 M sodium pyrophosphate to residue agitate for 1 hour centrifuge decant add to first split and bring to 50 mL volume with DIW Analyze extract by ICP-MS (Extract 3)

Figure 5 Schematic of sequential extraction procedure After extract step 5 half of sample was digested and analyzed by ICP-MS and HG-AAS and the other half was treated in step 6 Because of the potential volatilization of sulfide and selenides in step 6 element concentrations in extract 6 were calculated from the difference between the concentration in the residue from step 5 and that in residue from step 6

bull Step 4 (amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides) Mix residue with 25 mL 025 M NH2OHmiddotHCl (hydroxylamine hydrochloride)- 010 M HCl for 30 minutes in a water bath at 50-54ordmC Stir occasionally Centrifuge decant and fill to 50 mL with DIW Add 500 microL concentrated ultrapure HNO3

and analyze by ICP-MS (Extract 4)

bull Step 5 (crystalline iron-oxides) Combine residue with 20 mL 10 M NH2OHmiddotHCl in 25 acetic acid Cap and shake Place in boiling water (~90ordm C) bath for 3 hours uncapped mix occasionally Centrifuge and decant Rinse residue with 10 mL 25 acetic acid by handshyshaking and then centrifuge and decant into first split Carry out a second leach with 20 mL 10 M NH2OHmiddotHCl in 25 acetic acid but heat in boiling water bath for 15 hours Mix occasionally Centrifuge and decant into first split Fill to 50 mL with DIW Analyze extract by ICP-MS (Extract 5)

bull Residue 5 (sulfides and selenides and residual material) Dry residue at approximately 100degF (~38degC) and then disaggregate to homogenize Split residue in half Digest half of sample with mixture of concentrated acids and analyze by ICP-MS and HG-AAS (Residue 5) Treat other half of residue in next step

bull Step 6 (sulfides and selenides- acid volatile phases volatilized step may potentially attack surfaces corners or edges of silicate minerals) Add 05 g of KClO3 to residue and mix Slowly add 10 mL concentrated HCl and mix Let sit for 45 minutes with occasional gentle shaking Add 10 mL of DIW mix centrifuge and discard To the residue add 10 mL 4 N HNO3 and heat in boiling water bath for 20 minutes centrifuge and discard Add 10 mL DIW shake and centrifuge for 10 minutes also discard Because some sulfide and selenides may be volatilized calculate step 6 fraction by subtracting element concentration in residue from step 5 from concentrations in residue from step 6 (Residue 5 ndash Residue 6)

bull Step 7 (residual material) Dry residue at approximately 100degF (~38degC) Digest sample with mixture of concentrated acids and analyze by ICP-MS and HG-AAS (Residue 6)

Results

Mineralogy

The quantitative mineralogy of the original unleached samples and residues after extraction steps 5 (residue 5) and 6 (residue 6) are given in Appendix 1 The relative amounts of phases in each sample in weight percent (wt ) were for the crystalline part of the sample only The percentages of phases in the residues were normalized with respect to weight loss due to the dissolution of the various phases during the previous extraction steps This measured weight loss in weight percent is given in Appendix 1 The detection limit for XRD was on the order of a few weight percent and therefore phases present in trace amounts were likely below reliable detection

Most samples primarily were composed of silicates including quartz feldspar (albite anorthite labradorite microcline orthoclase) hornblende mica (muscovite) chlorite and clay (kaolin vermiculite and vermiculite-type mixed layer clay) The mineralogy of the residues suggested that most of these silicates were resistant to the extraction reagents The exceptions were several clay minerals such as vermiculite and the vermiculite-type mixed layer clay and in some cases hornblende The vermiculite-type mixed layer clay had an intense broad peak at a spacing of approximately 115 to 120 Aring which was assigned to sepiolite by the XRD phase matching software Sepiolite commonly forms in shallow seas and lakes and is not likely to be found in mine waste so this peak was likely from a hydrous altered biotite (Poppe and others 2001) According to Rebertus and others (1986) biotite weathers to interstratified biotiteshyvermiculite (hydrobiotite) thus this low angle peak may have been the result of varying degrees of biotite alteration

The only sample that contained significant carbonate was the tailings from the Callahan Mine (CLHN-TP-2) having nearly 20 wt calcite The second step using acetic acid aimed at dissolving carbonate minerals such as calcite [CaCO3] and dolomite [CaMg(CO3)2] (Kulp and Pratt 2004) The residue remaining after step 5 did not contain detectable calcite dissolution of calcite had taken place between steps 1 and 5

Step 4 of the extraction procedure targeted amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides (Chao 1972 Chao and Zhou 1983 Hall and others 1996a) No crystalline manganese-oxide phases were detected by XRD The crystalline Fe-oxide and Fe-hydroxysulfate minerals found in these samples included goethite [FeOOH] hematite [Fe2O3] and jarosite [K2Fe6(SO4)4(OH)12] Chester and Hughes (1967) reported the dissolution of crystalline iron-oxide minerals (goethite and hematite) using the reagents in step 5 Only partial dissolution of jarosite was expected based on a study by Filipek and Theobald (1981) Based on the mineralogy of residue 5 the reagents in steps 1 through 5 did not generally digest hematite and only partially digested goethite and jarosite (Appendix 1)

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

Sequential Extractions

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

The sum of the concentrations of an element leached from the solids in steps 1 through 5 plus the residue after step 5 (calculated total) should be equal to the original total element concentration of the solid (bulk total) The calculated total from the extractions generally correlated with the original unleached concentration for most of the major elements Figure 6 shows these correlations for iron and calcium with the bulk total shown on the x-axis and the calculated total shown on the y-axis As shown many values plot within the plusmn 10 analytical uncertainty associated with the ICP-MS The stream sediment from the Pike Hill Copper Mine is anomalous in figure 6 For calcium the sum of extractions 1 through 5 plus residue 5 falls within an acceptable range but for nearly all samples the concentration in residue 6 was higher than in the original sample (not shown) Therefore the data for residue 6 for calcium were considered invalid and extract steps 6 and 7 were grouped together (sulfideselenide and residual fractions) This was also applied to magnesium and manganese because a significant amount of samples contained higher concentrations of these elements in the final residue (residue 6) compared to the unleached sample A reagent that contained sodium was used in step 3 so concentrations in extracts after this step were not examined The concentrations of sodium in extracts 1 and 2 were at or below the detection limit for all samples except the tailings from the Martha Mine Most aluminum was higher in the summed concentrations compared to the bulk

concentration and for nearly all the samples the concentration in residue 6 was higher than in the original This suggests one of the reagents may have been contaminated with aluminum

Figure 6 Calculated iron (Fe) and calcium (Ca) totals from extractions versus total from untreated samples Calculated totals are the sum of an element in extracts 1 2 3 4 and 5 and in the residue after step 5 Zero was used for concentrations less than the detection limit The black line represents a 11 correlation and the red dashed lines represent the analytical uncertainty of plusmn 10

The calculated totals for trace elements generally correlated with concentrations in the unleached sample In figure 7 the concentrations of arsenic copper selenium and zinc for most samples fall within the plusmn 10 ICP-MS and HG-AAS analytical uncertainties As with iron and calcium the Pike Hill stream sediment is anomalous for copper and zinc The results of the sequential extraction on other trace elements such as cadmium cobalt lead and nickel also were reasonable because calculated totals generally correlated with the original bulk concentrations Based on these comparisons the validity of the data from the extractions was assessed For most elements the extraction results were within the acceptable range of error Future reports will interpret the results of the sequential extractions in more detail

Methods

Mineralogy

Minerals were identified by powder X-ray diffraction analysis (XRD) Diffraction patterns were collected using a Scintag X1 automated powder diffractometer equipped with a Peltier detector with CuKα radiation The XRD patterns were analyzed using Material Data Incrsquos JADE software and standard reference patterns Relative amounts of phases were estimated using the Siroquant computer program which utilizes the full XRD profile in a Rietveld refinement (Taylor and Clapp 1992) The analytical uncertainty of the Siroquant results is approximately plusmn 5 wt The colors of the samples given in table 1 were determined using soil color charts (Munsell Soil Color Charts 1994)

Sequential Extractions

Seven-step sequential extractions were done on nineteen mine-waste and stream-sediment samples on three duplicates and on two blanks (table 1) One blank was used for analytical calibration purposes (Extract ID lsquoArsquo in table 1) Samples were either grab or composites Most composites consisted of a minimum of 30 sample increments sampled over a measured area divided into a stratified grid One stream-sediment composite (Ely-SD-09) consisted of three increments from different depositional areas in the stream Samples were air-dried sieved to lt2 mm (or lt180 μm for sample 1139830-SD stream sediment from Pike Hill) and homogenized (table 1) After digestion by a mixture of HCl-HNO3-HClO4-HF a split of the original untreated sample was analyzed by inductively coupled plasma-mass spectrometry (ICPshyMS) to determine the major- and trace-element composition (Briggs and Meier 2002) A split of the original untreated sample was also analyzed by hydride-generation atomic absorption spectrometry (HG-AAS) to determine the concentration of Se after the sample was digested with a mixture of HNO3-HF-HClO4 (Hageman and others 2002) Residues remaining after extraction steps 5 and 6 were analyzed after digestion by ICP-MS and HG-AAS Extraction solutes were analyzed by ICP-MS (Lamothe and others 2002) The analyses were done in US Geological Survey (USGS) laboratories in Denver Colo The accuracy of both methods was approximately plusmn10

The distribution of elements determined by sequential extractions were operationally defined by the reagents used the reaction times temperatures and solid-to-extraction solution ratio for each step No single reagent time and temperature combination could be applied to all sample types to recover a given phase extractions were matrix-dependent This extraction procedure also attempted to differentiate the amorphous (step 4) versus crystalline (step 5) iron-oxide and iron-hydroxide phases There is a gradation from amorphous to cryptocrystalline to crystalline iron-oxides and hydroxides Hall and others (1996a) discussed the subtleties in differentiating among the phases depending on reagent strength Additional complicating factors included the possibility that occluded grains might persist past their designated dissolution step or factors such as grain size mineralogy or solid solution may affect the reactivity of phases The sequential extraction procedure used in this study is outlined below and illustrated in figure 5 The procedure was a combination of methods developed by Chao (1972) Chao and Sanzolone (1977 1989) Chao and Zhou (1983) Chester and Hughes (1967) Hall and others (1996a b) and Kulp and Pratt (2004) The hypothetically targeted species in each step are given in italics

Results

Mineralogy

The quantitative mineralogy of the original unleached samples and residues after extraction steps 5 (residue 5) and 6 (residue 6) are given in Appendix 1 The relative amounts of phases in each sample in weight percent (wt ) were for the crystalline part of the sample only The percentages of phases in the residues were normalized with respect to weight loss due to the dissolution of the various phases during the previous extraction steps This measured weight loss in weight percent is given in Appendix 1 The detection limit for XRD was on the order of a few weight percent and therefore phases present in trace amounts were likely below reliable detection

Most samples primarily were composed of silicates including quartz feldspar (albite anorthite labradorite microcline orthoclase) hornblende mica (muscovite) chlorite and clay (kaolin vermiculite and vermiculite-type mixed layer clay) The mineralogy of the residues suggested that most of these silicates were resistant to the extraction reagents The exceptions were several clay minerals such as vermiculite and the vermiculite-type mixed layer clay and in some cases hornblende The vermiculite-type mixed layer clay had an intense broad peak at a spacing of approximately 115 to 120 Aring which was assigned to sepiolite by the XRD phase matching software Sepiolite commonly forms in shallow seas and lakes and is not likely to be found in mine waste so this peak was likely from a hydrous altered biotite (Poppe and others 2001) According to Rebertus and others (1986) biotite weathers to interstratified biotiteshyvermiculite (hydrobiotite) thus this low angle peak may have been the result of varying degrees of biotite alteration

The only sample that contained significant carbonate was the tailings from the Callahan Mine (CLHN-TP-2) having nearly 20 wt calcite The second step using acetic acid aimed at dissolving carbonate minerals such as calcite [CaCO3] and dolomite [CaMg(CO3)2] (Kulp and Pratt 2004) The residue remaining after step 5 did not contain detectable calcite dissolution of calcite had taken place between steps 1 and 5

Step 4 of the extraction procedure targeted amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides (Chao 1972 Chao and Zhou 1983 Hall and others 1996a) No crystalline manganese-oxide phases were detected by XRD The crystalline Fe-oxide and Fe-hydroxysulfate minerals found in these samples included goethite [FeOOH] hematite [Fe2O3] and jarosite [K2Fe6(SO4)4(OH)12] Chester and Hughes (1967) reported the dissolution of crystalline iron-oxide minerals (goethite and hematite) using the reagents in step 5 Only partial dissolution of jarosite was expected based on a study by Filipek and Theobald (1981) Based on the mineralogy of residue 5 the reagents in steps 1 through 5 did not generally digest hematite and only partially digested goethite and jarosite (Appendix 1)

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

Sequential Extractions

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

The sum of the concentrations of an element leached from the solids in steps 1 through 5 plus the residue after step 5 (calculated total) should be equal to the original total element concentration of the solid (bulk total) The calculated total from the extractions generally correlated with the original unleached concentration for most of the major elements Figure 6 shows these correlations for iron and calcium with the bulk total shown on the x-axis and the calculated total shown on the y-axis As shown many values plot within the plusmn 10 analytical uncertainty associated with the ICP-MS The stream sediment from the Pike Hill Copper Mine is anomalous in figure 6 For calcium the sum of extractions 1 through 5 plus residue 5 falls within an acceptable range but for nearly all samples the concentration in residue 6 was higher than in the original sample (not shown) Therefore the data for residue 6 for calcium were considered invalid and extract steps 6 and 7 were grouped together (sulfideselenide and residual fractions) This was also applied to magnesium and manganese because a significant amount of samples contained higher concentrations of these elements in the final residue (residue 6) compared to the unleached sample A reagent that contained sodium was used in step 3 so concentrations in extracts after this step were not examined The concentrations of sodium in extracts 1 and 2 were at or below the detection limit for all samples except the tailings from the Martha Mine Most aluminum was higher in the summed concentrations compared to the bulk

concentration and for nearly all the samples the concentration in residue 6 was higher than in the original This suggests one of the reagents may have been contaminated with aluminum

Figure 6 Calculated iron (Fe) and calcium (Ca) totals from extractions versus total from untreated samples Calculated totals are the sum of an element in extracts 1 2 3 4 and 5 and in the residue after step 5 Zero was used for concentrations less than the detection limit The black line represents a 11 correlation and the red dashed lines represent the analytical uncertainty of plusmn 10

The calculated totals for trace elements generally correlated with concentrations in the unleached sample In figure 7 the concentrations of arsenic copper selenium and zinc for most samples fall within the plusmn 10 ICP-MS and HG-AAS analytical uncertainties As with iron and calcium the Pike Hill stream sediment is anomalous for copper and zinc The results of the sequential extraction on other trace elements such as cadmium cobalt lead and nickel also were reasonable because calculated totals generally correlated with the original bulk concentrations Based on these comparisons the validity of the data from the extractions was assessed For most elements the extraction results were within the acceptable range of error Future reports will interpret the results of the sequential extractions in more detail

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

Sequential Extractions

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

The sum of the concentrations of an element leached from the solids in steps 1 through 5 plus the residue after step 5 (calculated total) should be equal to the original total element concentration of the solid (bulk total) The calculated total from the extractions generally correlated with the original unleached concentration for most of the major elements Figure 6 shows these correlations for iron and calcium with the bulk total shown on the x-axis and the calculated total shown on the y-axis As shown many values plot within the plusmn 10 analytical uncertainty associated with the ICP-MS The stream sediment from the Pike Hill Copper Mine is anomalous in figure 6 For calcium the sum of extractions 1 through 5 plus residue 5 falls within an acceptable range but for nearly all samples the concentration in residue 6 was higher than in the original sample (not shown) Therefore the data for residue 6 for calcium were considered invalid and extract steps 6 and 7 were grouped together (sulfideselenide and residual fractions) This was also applied to magnesium and manganese because a significant amount of samples contained higher concentrations of these elements in the final residue (residue 6) compared to the unleached sample A reagent that contained sodium was used in step 3 so concentrations in extracts after this step were not examined The concentrations of sodium in extracts 1 and 2 were at or below the detection limit for all samples except the tailings from the Martha Mine Most aluminum was higher in the summed concentrations compared to the bulk

concentration and for nearly all the samples the concentration in residue 6 was higher than in the original This suggests one of the reagents may have been contaminated with aluminum

Figure 6 Calculated iron (Fe) and calcium (Ca) totals from extractions versus total from untreated samples Calculated totals are the sum of an element in extracts 1 2 3 4 and 5 and in the residue after step 5 Zero was used for concentrations less than the detection limit The black line represents a 11 correlation and the red dashed lines represent the analytical uncertainty of plusmn 10

The calculated totals for trace elements generally correlated with concentrations in the unleached sample In figure 7 the concentrations of arsenic copper selenium and zinc for most samples fall within the plusmn 10 ICP-MS and HG-AAS analytical uncertainties As with iron and calcium the Pike Hill stream sediment is anomalous for copper and zinc The results of the sequential extraction on other trace elements such as cadmium cobalt lead and nickel also were reasonable because calculated totals generally correlated with the original bulk concentrations Based on these comparisons the validity of the data from the extractions was assessed For most elements the extraction results were within the acceptable range of error Future reports will interpret the results of the sequential extractions in more detail

Methods

Mineralogy

Minerals were identified by powder X-ray diffraction analysis (XRD) Diffraction patterns were collected using a Scintag X1 automated powder diffractometer equipped with a Peltier detector with CuKα radiation The XRD patterns were analyzed using Material Data Incrsquos JADE software and standard reference patterns Relative amounts of phases were estimated using the Siroquant computer program which utilizes the full XRD profile in a Rietveld refinement (Taylor and Clapp 1992) The analytical uncertainty of the Siroquant results is approximately plusmn 5 wt The colors of the samples given in table 1 were determined using soil color charts (Munsell Soil Color Charts 1994)

Sequential Extractions

Seven-step sequential extractions were done on nineteen mine-waste and stream-sediment samples on three duplicates and on two blanks (table 1) One blank was used for analytical calibration purposes (Extract ID lsquoArsquo in table 1) Samples were either grab or composites Most composites consisted of a minimum of 30 sample increments sampled over a measured area divided into a stratified grid One stream-sediment composite (Ely-SD-09) consisted of three increments from different depositional areas in the stream Samples were air-dried sieved to lt2 mm (or lt180 μm for sample 1139830-SD stream sediment from Pike Hill) and homogenized (table 1) After digestion by a mixture of HCl-HNO3-HClO4-HF a split of the original untreated sample was analyzed by inductively coupled plasma-mass spectrometry (ICPshyMS) to determine the major- and trace-element composition (Briggs and Meier 2002) A split of the original untreated sample was also analyzed by hydride-generation atomic absorption spectrometry (HG-AAS) to determine the concentration of Se after the sample was digested with a mixture of HNO3-HF-HClO4 (Hageman and others 2002) Residues remaining after extraction steps 5 and 6 were analyzed after digestion by ICP-MS and HG-AAS Extraction solutes were analyzed by ICP-MS (Lamothe and others 2002) The analyses were done in US Geological Survey (USGS) laboratories in Denver Colo The accuracy of both methods was approximately plusmn10

The distribution of elements determined by sequential extractions were operationally defined by the reagents used the reaction times temperatures and solid-to-extraction solution ratio for each step No single reagent time and temperature combination could be applied to all sample types to recover a given phase extractions were matrix-dependent This extraction procedure also attempted to differentiate the amorphous (step 4) versus crystalline (step 5) iron-oxide and iron-hydroxide phases There is a gradation from amorphous to cryptocrystalline to crystalline iron-oxides and hydroxides Hall and others (1996a) discussed the subtleties in differentiating among the phases depending on reagent strength Additional complicating factors included the possibility that occluded grains might persist past their designated dissolution step or factors such as grain size mineralogy or solid solution may affect the reactivity of phases The sequential extraction procedure used in this study is outlined below and illustrated in figure 5 The procedure was a combination of methods developed by Chao (1972) Chao and Sanzolone (1977 1989) Chao and Zhou (1983) Chester and Hughes (1967) Hall and others (1996a b) and Kulp and Pratt (2004) The hypothetically targeted species in each step are given in italics

bull Step 1 (soluble adsorbed and exchangeable fraction) Combine 10 g of sample with 25 mL 01 M KH2PO4 agitate for 2 hours at 25ordmC Centrifuge for 10 minutes (15000 rpm Sorvall RC2-B refrigerated supercentrifuge) decant extract and dilute with deionized water (DIW) to 50 mL Add 500 microL concentrated ultrapure HNO3 Analyze extract by ICP-MS (Extract 1)

bull Step 2 (carbonates) Combine residue with 25 mL 15 acetic acid agitate for 2 hours centrifuge decant fill to 50 mL volume with DIW Analyze extract by ICP-MS (Extract 2)

bull Step 3 (organic material) Combine residue with 25 mL 01 M sodium pyrophosphate and agitate for 1 hour Centrifuge and decant Add another 25 mL 01 M sodium pyrophosphate to residue agitate for 1 hour centrifuge decant add to first split and bring to 50 mL volume with DIW Analyze extract by ICP-MS (Extract 3)

Figure 5 Schematic of sequential extraction procedure After extract step 5 half of sample was digested and analyzed by ICP-MS and HG-AAS and the other half was treated in step 6 Because of the potential volatilization of sulfide and selenides in step 6 element concentrations in extract 6 were calculated from the difference between the concentration in the residue from step 5 and that in residue from step 6

bull Step 4 (amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides) Mix residue with 25 mL 025 M NH2OHmiddotHCl (hydroxylamine hydrochloride)- 010 M HCl for 30 minutes in a water bath at 50-54ordmC Stir occasionally Centrifuge decant and fill to 50 mL with DIW Add 500 microL concentrated ultrapure HNO3

and analyze by ICP-MS (Extract 4)

bull Step 5 (crystalline iron-oxides) Combine residue with 20 mL 10 M NH2OHmiddotHCl in 25 acetic acid Cap and shake Place in boiling water (~90ordm C) bath for 3 hours uncapped mix occasionally Centrifuge and decant Rinse residue with 10 mL 25 acetic acid by handshyshaking and then centrifuge and decant into first split Carry out a second leach with 20 mL 10 M NH2OHmiddotHCl in 25 acetic acid but heat in boiling water bath for 15 hours Mix occasionally Centrifuge and decant into first split Fill to 50 mL with DIW Analyze extract by ICP-MS (Extract 5)

bull Residue 5 (sulfides and selenides and residual material) Dry residue at approximately 100degF (~38degC) and then disaggregate to homogenize Split residue in half Digest half of sample with mixture of concentrated acids and analyze by ICP-MS and HG-AAS (Residue 5) Treat other half of residue in next step

bull Step 6 (sulfides and selenides- acid volatile phases volatilized step may potentially attack surfaces corners or edges of silicate minerals) Add 05 g of KClO3 to residue and mix Slowly add 10 mL concentrated HCl and mix Let sit for 45 minutes with occasional gentle shaking Add 10 mL of DIW mix centrifuge and discard To the residue add 10 mL 4 N HNO3 and heat in boiling water bath for 20 minutes centrifuge and discard Add 10 mL DIW shake and centrifuge for 10 minutes also discard Because some sulfide and selenides may be volatilized calculate step 6 fraction by subtracting element concentration in residue from step 5 from concentrations in residue from step 6 (Residue 5 ndash Residue 6)

bull Step 7 (residual material) Dry residue at approximately 100degF (~38degC) Digest sample with mixture of concentrated acids and analyze by ICP-MS and HG-AAS (Residue 6)

Results

Mineralogy

The quantitative mineralogy of the original unleached samples and residues after extraction steps 5 (residue 5) and 6 (residue 6) are given in Appendix 1 The relative amounts of phases in each sample in weight percent (wt ) were for the crystalline part of the sample only The percentages of phases in the residues were normalized with respect to weight loss due to the dissolution of the various phases during the previous extraction steps This measured weight loss in weight percent is given in Appendix 1 The detection limit for XRD was on the order of a few weight percent and therefore phases present in trace amounts were likely below reliable detection

Most samples primarily were composed of silicates including quartz feldspar (albite anorthite labradorite microcline orthoclase) hornblende mica (muscovite) chlorite and clay (kaolin vermiculite and vermiculite-type mixed layer clay) The mineralogy of the residues suggested that most of these silicates were resistant to the extraction reagents The exceptions were several clay minerals such as vermiculite and the vermiculite-type mixed layer clay and in some cases hornblende The vermiculite-type mixed layer clay had an intense broad peak at a spacing of approximately 115 to 120 Aring which was assigned to sepiolite by the XRD phase matching software Sepiolite commonly forms in shallow seas and lakes and is not likely to be found in mine waste so this peak was likely from a hydrous altered biotite (Poppe and others 2001) According to Rebertus and others (1986) biotite weathers to interstratified biotiteshyvermiculite (hydrobiotite) thus this low angle peak may have been the result of varying degrees of biotite alteration

The only sample that contained significant carbonate was the tailings from the Callahan Mine (CLHN-TP-2) having nearly 20 wt calcite The second step using acetic acid aimed at dissolving carbonate minerals such as calcite [CaCO3] and dolomite [CaMg(CO3)2] (Kulp and Pratt 2004) The residue remaining after step 5 did not contain detectable calcite dissolution of calcite had taken place between steps 1 and 5

Step 4 of the extraction procedure targeted amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides (Chao 1972 Chao and Zhou 1983 Hall and others 1996a) No crystalline manganese-oxide phases were detected by XRD The crystalline Fe-oxide and Fe-hydroxysulfate minerals found in these samples included goethite [FeOOH] hematite [Fe2O3] and jarosite [K2Fe6(SO4)4(OH)12] Chester and Hughes (1967) reported the dissolution of crystalline iron-oxide minerals (goethite and hematite) using the reagents in step 5 Only partial dissolution of jarosite was expected based on a study by Filipek and Theobald (1981) Based on the mineralogy of residue 5 the reagents in steps 1 through 5 did not generally digest hematite and only partially digested goethite and jarosite (Appendix 1)

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

concentration and for nearly all the samples the concentration in residue 6 was higher than in the original This suggests one of the reagents may have been contaminated with aluminum

Methods

Mineralogy

Minerals were identified by powder X-ray diffraction analysis (XRD) Diffraction patterns were collected using a Scintag X1 automated powder diffractometer equipped with a Peltier detector with CuKα radiation The XRD patterns were analyzed using Material Data Incrsquos JADE software and standard reference patterns Relative amounts of phases were estimated using the Siroquant computer program which utilizes the full XRD profile in a Rietveld refinement (Taylor and Clapp 1992) The analytical uncertainty of the Siroquant results is approximately plusmn 5 wt The colors of the samples given in table 1 were determined using soil color charts (Munsell Soil Color Charts 1994)

Sequential Extractions

Seven-step sequential extractions were done on nineteen mine-waste and stream-sediment samples on three duplicates and on two blanks (table 1) One blank was used for analytical calibration purposes (Extract ID lsquoArsquo in table 1) Samples were either grab or composites Most composites consisted of a minimum of 30 sample increments sampled over a measured area divided into a stratified grid One stream-sediment composite (Ely-SD-09) consisted of three increments from different depositional areas in the stream Samples were air-dried sieved to lt2 mm (or lt180 μm for sample 1139830-SD stream sediment from Pike Hill) and homogenized (table 1) After digestion by a mixture of HCl-HNO3-HClO4-HF a split of the original untreated sample was analyzed by inductively coupled plasma-mass spectrometry (ICPshyMS) to determine the major- and trace-element composition (Briggs and Meier 2002) A split of the original untreated sample was also analyzed by hydride-generation atomic absorption spectrometry (HG-AAS) to determine the concentration of Se after the sample was digested with a mixture of HNO3-HF-HClO4 (Hageman and others 2002) Residues remaining after extraction steps 5 and 6 were analyzed after digestion by ICP-MS and HG-AAS Extraction solutes were analyzed by ICP-MS (Lamothe and others 2002) The analyses were done in US Geological Survey (USGS) laboratories in Denver Colo The accuracy of both methods was approximately plusmn10

The distribution of elements determined by sequential extractions were operationally defined by the reagents used the reaction times temperatures and solid-to-extraction solution ratio for each step No single reagent time and temperature combination could be applied to all sample types to recover a given phase extractions were matrix-dependent This extraction procedure also attempted to differentiate the amorphous (step 4) versus crystalline (step 5) iron-oxide and iron-hydroxide phases There is a gradation from amorphous to cryptocrystalline to crystalline iron-oxides and hydroxides Hall and others (1996a) discussed the subtleties in differentiating among the phases depending on reagent strength Additional complicating factors included the possibility that occluded grains might persist past their designated dissolution step or factors such as grain size mineralogy or solid solution may affect the reactivity of phases The sequential extraction procedure used in this study is outlined below and illustrated in figure 5 The procedure was a combination of methods developed by Chao (1972) Chao and Sanzolone (1977 1989) Chao and Zhou (1983) Chester and Hughes (1967) Hall and others (1996a b) and Kulp and Pratt (2004) The hypothetically targeted species in each step are given in italics

Results

Mineralogy

The quantitative mineralogy of the original unleached samples and residues after extraction steps 5 (residue 5) and 6 (residue 6) are given in Appendix 1 The relative amounts of phases in each sample in weight percent (wt ) were for the crystalline part of the sample only The percentages of phases in the residues were normalized with respect to weight loss due to the dissolution of the various phases during the previous extraction steps This measured weight loss in weight percent is given in Appendix 1 The detection limit for XRD was on the order of a few weight percent and therefore phases present in trace amounts were likely below reliable detection

Most samples primarily were composed of silicates including quartz feldspar (albite anorthite labradorite microcline orthoclase) hornblende mica (muscovite) chlorite and clay (kaolin vermiculite and vermiculite-type mixed layer clay) The mineralogy of the residues suggested that most of these silicates were resistant to the extraction reagents The exceptions were several clay minerals such as vermiculite and the vermiculite-type mixed layer clay and in some cases hornblende The vermiculite-type mixed layer clay had an intense broad peak at a spacing of approximately 115 to 120 Aring which was assigned to sepiolite by the XRD phase matching software Sepiolite commonly forms in shallow seas and lakes and is not likely to be found in mine waste so this peak was likely from a hydrous altered biotite (Poppe and others 2001) According to Rebertus and others (1986) biotite weathers to interstratified biotiteshyvermiculite (hydrobiotite) thus this low angle peak may have been the result of varying degrees of biotite alteration

The only sample that contained significant carbonate was the tailings from the Callahan Mine (CLHN-TP-2) having nearly 20 wt calcite The second step using acetic acid aimed at dissolving carbonate minerals such as calcite [CaCO3] and dolomite [CaMg(CO3)2] (Kulp and Pratt 2004) The residue remaining after step 5 did not contain detectable calcite dissolution of calcite had taken place between steps 1 and 5

Step 4 of the extraction procedure targeted amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides (Chao 1972 Chao and Zhou 1983 Hall and others 1996a) No crystalline manganese-oxide phases were detected by XRD The crystalline Fe-oxide and Fe-hydroxysulfate minerals found in these samples included goethite [FeOOH] hematite [Fe2O3] and jarosite [K2Fe6(SO4)4(OH)12] Chester and Hughes (1967) reported the dissolution of crystalline iron-oxide minerals (goethite and hematite) using the reagents in step 5 Only partial dissolution of jarosite was expected based on a study by Filipek and Theobald (1981) Based on the mineralogy of residue 5 the reagents in steps 1 through 5 did not generally digest hematite and only partially digested goethite and jarosite (Appendix 1)

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

Sequential Extractions

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

The sum of the concentrations of an element leached from the solids in steps 1 through 5 plus the residue after step 5 (calculated total) should be equal to the original total element concentration of the solid (bulk total) The calculated total from the extractions generally correlated with the original unleached concentration for most of the major elements Figure 6 shows these correlations for iron and calcium with the bulk total shown on the x-axis and the calculated total shown on the y-axis As shown many values plot within the plusmn 10 analytical uncertainty associated with the ICP-MS The stream sediment from the Pike Hill Copper Mine is anomalous in figure 6 For calcium the sum of extractions 1 through 5 plus residue 5 falls within an acceptable range but for nearly all samples the concentration in residue 6 was higher than in the original sample (not shown) Therefore the data for residue 6 for calcium were considered invalid and extract steps 6 and 7 were grouped together (sulfideselenide and residual fractions) This was also applied to magnesium and manganese because a significant amount of samples contained higher concentrations of these elements in the final residue (residue 6) compared to the unleached sample A reagent that contained sodium was used in step 3 so concentrations in extracts after this step were not examined The concentrations of sodium in extracts 1 and 2 were at or below the detection limit for all samples except the tailings from the Martha Mine Most aluminum was higher in the summed concentrations compared to the bulk

concentration and for nearly all the samples the concentration in residue 6 was higher than in the original This suggests one of the reagents may have been contaminated with aluminum

Figure 6 Calculated iron (Fe) and calcium (Ca) totals from extractions versus total from untreated samples Calculated totals are the sum of an element in extracts 1 2 3 4 and 5 and in the residue after step 5 Zero was used for concentrations less than the detection limit The black line represents a 11 correlation and the red dashed lines represent the analytical uncertainty of plusmn 10

The calculated totals for trace elements generally correlated with concentrations in the unleached sample In figure 7 the concentrations of arsenic copper selenium and zinc for most samples fall within the plusmn 10 ICP-MS and HG-AAS analytical uncertainties As with iron and calcium the Pike Hill stream sediment is anomalous for copper and zinc The results of the sequential extraction on other trace elements such as cadmium cobalt lead and nickel also were reasonable because calculated totals generally correlated with the original bulk concentrations Based on these comparisons the validity of the data from the extractions was assessed For most elements the extraction results were within the acceptable range of error Future reports will interpret the results of the sequential extractions in more detail

Most samples primarily were composed of silicates including quartz feldspar (albite anorthite labradorite microcline orthoclase) hornblende mica (muscovite) chlorite and clay (kaolin vermiculite and vermiculite-type mixed layer clay) The mineralogy of the residues suggested that most of these silicates were resistant to the extraction reagents The exceptions were several clay minerals such as vermiculite and the vermiculite-type mixed layer clay and in some cases hornblende The vermiculite-type mixed layer clay had an intense broad peak at a spacing of approximately 115 to 120 Aring which was assigned to sepiolite by the XRD phase matching software Sepiolite commonly forms in shallow seas and lakes and is not likely to be found in mine waste so this peak was likely from a hydrous altered biotite (Poppe and others 2001) According to Rebertus and others (1986) biotite weathers to interstratified biotiteshyvermiculite (hydrobiotite) thus this low angle peak may have been the result of varying degrees of biotite alteration

The only sample that contained significant carbonate was the tailings from the Callahan Mine (CLHN-TP-2) having nearly 20 wt calcite The second step using acetic acid aimed at dissolving carbonate minerals such as calcite [CaCO3] and dolomite [CaMg(CO3)2] (Kulp and Pratt 2004) The residue remaining after step 5 did not contain detectable calcite dissolution of calcite had taken place between steps 1 and 5

Step 4 of the extraction procedure targeted amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides (Chao 1972 Chao and Zhou 1983 Hall and others 1996a) No crystalline manganese-oxide phases were detected by XRD The crystalline Fe-oxide and Fe-hydroxysulfate minerals found in these samples included goethite [FeOOH] hematite [Fe2O3] and jarosite [K2Fe6(SO4)4(OH)12] Chester and Hughes (1967) reported the dissolution of crystalline iron-oxide minerals (goethite and hematite) using the reagents in step 5 Only partial dissolution of jarosite was expected based on a study by Filipek and Theobald (1981) Based on the mineralogy of residue 5 the reagents in steps 1 through 5 did not generally digest hematite and only partially digested goethite and jarosite (Appendix 1)

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

Sequential Extractions

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

The sum of the concentrations of an element leached from the solids in steps 1 through 5 plus the residue after step 5 (calculated total) should be equal to the original total element concentration of the solid (bulk total) The calculated total from the extractions generally correlated with the original unleached concentration for most of the major elements Figure 6 shows these correlations for iron and calcium with the bulk total shown on the x-axis and the calculated total shown on the y-axis As shown many values plot within the plusmn 10 analytical uncertainty associated with the ICP-MS The stream sediment from the Pike Hill Copper Mine is anomalous in figure 6 For calcium the sum of extractions 1 through 5 plus residue 5 falls within an acceptable range but for nearly all samples the concentration in residue 6 was higher than in the original sample (not shown) Therefore the data for residue 6 for calcium were considered invalid and extract steps 6 and 7 were grouped together (sulfideselenide and residual fractions) This was also applied to magnesium and manganese because a significant amount of samples contained higher concentrations of these elements in the final residue (residue 6) compared to the unleached sample A reagent that contained sodium was used in step 3 so concentrations in extracts after this step were not examined The concentrations of sodium in extracts 1 and 2 were at or below the detection limit for all samples except the tailings from the Martha Mine Most aluminum was higher in the summed concentrations compared to the bulk

The calculated totals for trace elements generally correlated with concentrations in the unleached sample In figure 7 the concentrations of arsenic copper selenium and zinc for most samples fall within the plusmn 10 ICP-MS and HG-AAS analytical uncertainties As with iron and calcium the Pike Hill stream sediment is anomalous for copper and zinc The results of the sequential extraction on other trace elements such as cadmium cobalt lead and nickel also were reasonable because calculated totals generally correlated with the original bulk concentrations Based on these comparisons the validity of the data from the extractions was assessed For most elements the extraction results were within the acceptable range of error Future reports will interpret the results of the sequential extractions in more detail

Methods

Mineralogy

Minerals were identified by powder X-ray diffraction analysis (XRD) Diffraction patterns were collected using a Scintag X1 automated powder diffractometer equipped with a Peltier detector with CuKα radiation The XRD patterns were analyzed using Material Data Incrsquos JADE software and standard reference patterns Relative amounts of phases were estimated using the Siroquant computer program which utilizes the full XRD profile in a Rietveld refinement (Taylor and Clapp 1992) The analytical uncertainty of the Siroquant results is approximately plusmn 5 wt The colors of the samples given in table 1 were determined using soil color charts (Munsell Soil Color Charts 1994)

Sequential Extractions

Seven-step sequential extractions were done on nineteen mine-waste and stream-sediment samples on three duplicates and on two blanks (table 1) One blank was used for analytical calibration purposes (Extract ID lsquoArsquo in table 1) Samples were either grab or composites Most composites consisted of a minimum of 30 sample increments sampled over a measured area divided into a stratified grid One stream-sediment composite (Ely-SD-09) consisted of three increments from different depositional areas in the stream Samples were air-dried sieved to lt2 mm (or lt180 μm for sample 1139830-SD stream sediment from Pike Hill) and homogenized (table 1) After digestion by a mixture of HCl-HNO3-HClO4-HF a split of the original untreated sample was analyzed by inductively coupled plasma-mass spectrometry (ICPshyMS) to determine the major- and trace-element composition (Briggs and Meier 2002) A split of the original untreated sample was also analyzed by hydride-generation atomic absorption spectrometry (HG-AAS) to determine the concentration of Se after the sample was digested with a mixture of HNO3-HF-HClO4 (Hageman and others 2002) Residues remaining after extraction steps 5 and 6 were analyzed after digestion by ICP-MS and HG-AAS Extraction solutes were analyzed by ICP-MS (Lamothe and others 2002) The analyses were done in US Geological Survey (USGS) laboratories in Denver Colo The accuracy of both methods was approximately plusmn10

The distribution of elements determined by sequential extractions were operationally defined by the reagents used the reaction times temperatures and solid-to-extraction solution ratio for each step No single reagent time and temperature combination could be applied to all sample types to recover a given phase extractions were matrix-dependent This extraction procedure also attempted to differentiate the amorphous (step 4) versus crystalline (step 5) iron-oxide and iron-hydroxide phases There is a gradation from amorphous to cryptocrystalline to crystalline iron-oxides and hydroxides Hall and others (1996a) discussed the subtleties in differentiating among the phases depending on reagent strength Additional complicating factors included the possibility that occluded grains might persist past their designated dissolution step or factors such as grain size mineralogy or solid solution may affect the reactivity of phases The sequential extraction procedure used in this study is outlined below and illustrated in figure 5 The procedure was a combination of methods developed by Chao (1972) Chao and Sanzolone (1977 1989) Chao and Zhou (1983) Chester and Hughes (1967) Hall and others (1996a b) and Kulp and Pratt (2004) The hypothetically targeted species in each step are given in italics

Most samples primarily were composed of silicates including quartz feldspar (albite anorthite labradorite microcline orthoclase) hornblende mica (muscovite) chlorite and clay (kaolin vermiculite and vermiculite-type mixed layer clay) The mineralogy of the residues suggested that most of these silicates were resistant to the extraction reagents The exceptions were several clay minerals such as vermiculite and the vermiculite-type mixed layer clay and in some cases hornblende The vermiculite-type mixed layer clay had an intense broad peak at a spacing of approximately 115 to 120 Aring which was assigned to sepiolite by the XRD phase matching software Sepiolite commonly forms in shallow seas and lakes and is not likely to be found in mine waste so this peak was likely from a hydrous altered biotite (Poppe and others 2001) According to Rebertus and others (1986) biotite weathers to interstratified biotiteshyvermiculite (hydrobiotite) thus this low angle peak may have been the result of varying degrees of biotite alteration

The only sample that contained significant carbonate was the tailings from the Callahan Mine (CLHN-TP-2) having nearly 20 wt calcite The second step using acetic acid aimed at dissolving carbonate minerals such as calcite [CaCO3] and dolomite [CaMg(CO3)2] (Kulp and Pratt 2004) The residue remaining after step 5 did not contain detectable calcite dissolution of calcite had taken place between steps 1 and 5

Step 4 of the extraction procedure targeted amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides (Chao 1972 Chao and Zhou 1983 Hall and others 1996a) No crystalline manganese-oxide phases were detected by XRD The crystalline Fe-oxide and Fe-hydroxysulfate minerals found in these samples included goethite [FeOOH] hematite [Fe2O3] and jarosite [K2Fe6(SO4)4(OH)12] Chester and Hughes (1967) reported the dissolution of crystalline iron-oxide minerals (goethite and hematite) using the reagents in step 5 Only partial dissolution of jarosite was expected based on a study by Filipek and Theobald (1981) Based on the mineralogy of residue 5 the reagents in steps 1 through 5 did not generally digest hematite and only partially digested goethite and jarosite (Appendix 1)

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

Sequential Extractions

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

The sum of the concentrations of an element leached from the solids in steps 1 through 5 plus the residue after step 5 (calculated total) should be equal to the original total element concentration of the solid (bulk total) The calculated total from the extractions generally correlated with the original unleached concentration for most of the major elements Figure 6 shows these correlations for iron and calcium with the bulk total shown on the x-axis and the calculated total shown on the y-axis As shown many values plot within the plusmn 10 analytical uncertainty associated with the ICP-MS The stream sediment from the Pike Hill Copper Mine is anomalous in figure 6 For calcium the sum of extractions 1 through 5 plus residue 5 falls within an acceptable range but for nearly all samples the concentration in residue 6 was higher than in the original sample (not shown) Therefore the data for residue 6 for calcium were considered invalid and extract steps 6 and 7 were grouped together (sulfideselenide and residual fractions) This was also applied to magnesium and manganese because a significant amount of samples contained higher concentrations of these elements in the final residue (residue 6) compared to the unleached sample A reagent that contained sodium was used in step 3 so concentrations in extracts after this step were not examined The concentrations of sodium in extracts 1 and 2 were at or below the detection limit for all samples except the tailings from the Martha Mine Most aluminum was higher in the summed concentrations compared to the bulk

concentration and for nearly all the samples the concentration in residue 6 was higher than in the original This suggests one of the reagents may have been contaminated with aluminum

The calculated totals for trace elements generally correlated with concentrations in the unleached sample In figure 7 the concentrations of arsenic copper selenium and zinc for most samples fall within the plusmn 10 ICP-MS and HG-AAS analytical uncertainties As with iron and calcium the Pike Hill stream sediment is anomalous for copper and zinc The results of the sequential extraction on other trace elements such as cadmium cobalt lead and nickel also were reasonable because calculated totals generally correlated with the original bulk concentrations Based on these comparisons the validity of the data from the extractions was assessed For most elements the extraction results were within the acceptable range of error Future reports will interpret the results of the sequential extractions in more detail

The only sample that contained significant carbonate was the tailings from the Callahan Mine (CLHN-TP-2) having nearly 20 wt calcite The second step using acetic acid aimed at dissolving carbonate minerals such as calcite [CaCO3] and dolomite [CaMg(CO3)2] (Kulp and Pratt 2004) The residue remaining after step 5 did not contain detectable calcite dissolution of calcite had taken place between steps 1 and 5

Step 4 of the extraction procedure targeted amorphous iron- and aluminum-hydroxides and amorphous and crystalline manganese-oxides (Chao 1972 Chao and Zhou 1983 Hall and others 1996a) No crystalline manganese-oxide phases were detected by XRD The crystalline Fe-oxide and Fe-hydroxysulfate minerals found in these samples included goethite [FeOOH] hematite [Fe2O3] and jarosite [K2Fe6(SO4)4(OH)12] Chester and Hughes (1967) reported the dissolution of crystalline iron-oxide minerals (goethite and hematite) using the reagents in step 5 Only partial dissolution of jarosite was expected based on a study by Filipek and Theobald (1981) Based on the mineralogy of residue 5 the reagents in steps 1 through 5 did not generally digest hematite and only partially digested goethite and jarosite (Appendix 1)

Several samples contained minor to trace amounts of sulfides The reagents used in step 6 of the extraction procedure should have oxidized possibly volatilized and decomposed sulfides and selenides (Chao and Sanzolone 1977) Nearly all of the estimated 15 wt pyrrhotite in the unoxidized tailings from Elizabeth (TP1-S-unox) was digested after step 6 Pyrite was present in few weight percent for several samples and was broken down by reagents in step 6

Sequential Extractions

The concentrations of elements in unleached samples are given in Appendix 2 The concentrations of elements in extracts from steps 1 through 5 and in residues after steps 5 and 6 are given in Appendix 3 The amounts of an element extracted from the solid were calculated from the extract concentration and solid-to-extraction solution ratio The difference between the step 5 residue and the step 6 residue concentrations was the amount of an element extracted by step 6 solvents (selenidesulfide fraction see figure 5) Direct measurement of element concentrations in extract solution 6 was not used because some sulfides and selenides may have been volatilized by the acids utilized in step 6

The sum of the concentrations of an element leached from the solids in steps 1 through 5 plus the residue after step 5 (calculated total) should be equal to the original total element concentration of the solid (bulk total) The calculated total from the extractions generally correlated with the original unleached concentration for most of the major elements Figure 6 shows these correlations for iron and calcium with the bulk total shown on the x-axis and the calculated total shown on the y-axis As shown many values plot within the plusmn 10 analytical uncertainty associated with the ICP-MS The stream sediment from the Pike Hill Copper Mine is anomalous in figure 6 For calcium the sum of extractions 1 through 5 plus residue 5 falls within an acceptable range but for nearly all samples the concentration in residue 6 was higher than in the original sample (not shown) Therefore the data for residue 6 for calcium were considered invalid and extract steps 6 and 7 were grouped together (sulfideselenide and residual fractions) This was also applied to magnesium and manganese because a significant amount of samples contained higher concentrations of these elements in the final residue (residue 6) compared to the unleached sample A reagent that contained sodium was used in step 3 so concentrations in extracts after this step were not examined The concentrations of sodium in extracts 1 and 2 were at or below the detection limit for all samples except the tailings from the Martha Mine Most aluminum was higher in the summed concentrations compared to the bulk

concentration and for nearly all the samples the concentration in residue 6 was higher than in the original This suggests one of the reagents may have been contaminated with aluminum

Figure 6 Calculated iron (Fe) and calcium (Ca) totals from extractions versus total from untreated samples Calculated totals are the sum of an element in extracts 1 2 3 4 and 5 and in the residue after step 5 Zero was used for concentrations less than the detection limit The black line represents a 11 correlation and the red dashed lines represent the analytical uncertainty of plusmn 10

The calculated totals for trace elements generally correlated with concentrations in the unleached sample In figure 7 the concentrations of arsenic copper selenium and zinc for most samples fall within the plusmn 10 ICP-MS and HG-AAS analytical uncertainties As with iron and calcium the Pike Hill stream sediment is anomalous for copper and zinc The results of the sequential extraction on other trace elements such as cadmium cobalt lead and nickel also were reasonable because calculated totals generally correlated with the original bulk concentrations Based on these comparisons the validity of the data from the extractions was assessed For most elements the extraction results were within the acceptable range of error Future reports will interpret the results of the sequential extractions in more detail

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red

1 Explanation of results The concentrations in extracts 1 through 5 are presented as solid concentrations and were calculated from the extraction solution concentration and solid -to-extraction solution ratio The concentrations in residues remaining after steps 5 (5R) and 6 (6R) are for solids The sum of the solid phase results for extracts 1 through 5 plus extract 5R should sum to the total mass of the sample The subtraction of 6R from 5R represents the mass released to aqueous and gaseous phases by step 6 reagents (fig 5) 2 Results from ICP-MS analysis for all elements except Se concentrations in residues which were determined by HG-AAS 3 If the concentration of an element was near the detection limit in the blank concentrations were not corrected For samples with blank concentrations greater than the detection limit the concentration in the blank was subtracted from the concentration in the samples for a given extraction step and the detection limit became the concentration in the blank (shown in italics) 4 Concentrations of Cr and SiO2 in blanks for steps 2 and 5 were equal to or greater than many extract concentrations Data are invalid and shown in bold red
