The Committee acts as a forum for the exchange ofinformation on a number of initiatives aimed atrecruitment of engineers and technologists for the miningindustry.

The Phoenix programme, which is co-ordinated by theChamber of Mines of South Africa (COM), has focusedon the provision of resource packages for high schools.Details on the extraction of South African minerals areprovided as optional science subjects for Std 8. Packagesfor copper and manganese are already in use in manyschools, while gold and coal packages are underdevelopment Experiments are included, and the CaM isproviding training.

The University of Pretoria and the University of theWitwatersrand are collaborating with the teachers'training colleges in their respective cities on specialcourses for gifted children, aimed at introducing them tovarious aspects of the minerals industry. Thesearrangements include lectures and visits to mines andresearch facilities. Both programmes have been wellsupported

The University of the Witwatersrand is also offeringvacation work to schoolleavers; this is an integral part ofthe research effort in the Department of Metallurgy andMaterials Science. Project Seed, as it is called, requiresthe students to analyse information and to produce a smallreport.

The SAIMM supported the initiative of the Society ofProfessional Engineers (SPE) and the South AfricanEngineering Association (SAVI) on the development oftechnological man-power. Support has been obtained fromindustry and the Foundation for Research Development atthe highest level for the co-ordination of financial supportfor universities and technikons.

2. TECHNICAL MEETINGS

Portfolio Holder: Dr H. Scott-RusseUKey Performance Areas

In pursuance of its objectives regarding the dis-semination of technical information. the SA/MM

. organizes congresses. symposia. colloquia, schools,discussion groups. etc., to promote the transfer ofcurrent and new technology, and to satisfy the needs ofits members for continuing education by the exchangeof technical information. the communication of ideas.and the identification of technological problem areas.

The technical meetings held during the year-were orga-nized by the Mining, Extractive Metallurgy, and MetalsTechnology Groups, and the Special Interest Groups ofSurface Mining, Process Control, and Computer


Applications. The major event of the year was theInternational Deep Level Mining Conference.

In addition to the International Deep MiningConference (IDMC) , three events were held during theyear.

In July 1990, a school entitled 'Ventilation and Re-frigeration' was held over three days. Registereddelegates numbered 65, but attendance was somewhatlower. While excellent subject matter was presented at theschool, it is clear that, in the present economic climate,schools should be of shorter duration.

In May 1991, a one-day colloquium, entitled'Com-munications and Monitoring to Improve MineProductivity and Safety', was held. This proved to bepopular and attracted a full house of 103 delegates.Eleven interesting papers were squeezed into the day.

In June 1991, a school entitled 'Mine Valuation andGrade Control' was held over two days. The budget wasagain exceeded, 134 delegates attending.

Current planning is for a series of five one-daycolloquia to address productivity and survival in the gold-mining industry. Work has also started on twointernational conferences-the concurrent Mass Miningand Coal Mining Conferences to be held at the ElectraMining Exhibition in September 1992, and theInternational Backfill Conference to be held in 1993.

A two-day conference on 'Innovations in MetallurgicalPlant' was organized as a parallel session with 'DeepLevel Mining and Materials Engineering' at theInternational Deep Mining Conference held at NASRECfrom 17th to 21st September, 1990. The conference washeld in conjunction with the Electra Mining Exhibition. Atotal of 97 delegates attended the Extractive Metallurgysessions, and 20 papers were presented on a wide varietyof topics. Presenters included two overseas authors.

A three-day school on 'Practical Design of Com-

306 SEPTEMBER 1991

minution Processes' was held at Megawatt Park from 14thto 16th May, 1991. The objective of the school was toprovide a wider insight into modem theory and practicesemployed in the comminution routes, particularly forthose whose experience had previously been confinedmostly to Witwatersrand gold ores.

Mr Derek Barratt of Wright Engineers in Canada wasprincipal lecturer, and his lectures were complemented bycontributions from local experts to provide a SouthAfrican perspective. This successful school was attendedby 103 delegates, including the lecturers.

A one-day colloquium on 'Bacterial Oxidation' washeld on 18th June, 1991. Papers presented included 'Bio-oxidation of arsenopyrite and pyritic gold ores', 'Bacterialleaching of copper', and 'A review of the commissioningof several bio-oxidation plants'. A total of 84 delegatesattended.

A school on 'In-Pulp Technology' and a colloquiumon 'Industrial Minerals' are scheduled for the latter half of1991. The Special Interest Group on Process Control,which was formed during the previous year, had an activeprogramme, with visits arranged to JCI's Cooke Plant, theRustenburg Precious Metal Refinery, and Mintek.

The first South African colloquium on 'The EngineeringDevelopment of Composite Materials' took place at theIndaba Hotel on 23rd July, 1990. The Colloquium washeld in recognition of the major potential for application ofcomposite materials in South African industry, and provid-ed a forum where interested parties from industry couldmeet suppliers of composite materials. The fundamentalsof the production and performance of such materials alsoreceived a great deal of attention. The scientific approachwas introduced and well covered by the invited lecturer,Professor Adams from the University of Bristol, UK.

The Committee participated in the International DeepLevel Mining Conference and held a technical session on18th and 19th September, 1990 at NASREC. Thistechnical session, 'Application of Materials Engineeringin the Mining Industry' underlined the importance of thework carried out by materials engineers, and contributedto the forging of closer bonds between this discipline andthe mining industry.

The Committee also assisted the Publications Com-mittee in preparing the Proceedings of the FirstInternational Corex Conference for publication.

Conference was held over four days at the Electra MiningExhibition. Despite a severe downturn in the gold price atthat time, a total of 539 delegates attended; these included64 overseas delegates from a wide spread of countries.

The SAIMM was assisted in this venture by theAssociation of Mine Managers of South Africa, theAssociation of Mine Resident Engineers, and the SouthAfrican Institution of Mechanical Engineers. The input ofthese organizations, particularly with regard to thetechnical content of the Conference, was invaluable, andsincere thanks are due to all who were involved.

Twenty papers were presented in the category'Innovations in Metallurgical Plant', 22 papers under'Applications in Materials Engineering in the MiningIndustry', and 87 papers under 'Technical Challenges inDeep Level Mining'. The high standard of technicalcontent, presentation, and publication of the papers, aswell as the comprehensive technical coverage of theElectra Mining Exhibition, made this a most successfulevent.

The event was opened by the President of the Chamberof Mines of South Africa, Mc C.G. Knobbs. The Ministerof Mineral and Energy Affairs and Public Enterprises, DrDawie de Villiers, spoke at the banquet. Social eventswere well attended and enjoyed by the delegates.

The Conference volumes constitute an importantmining and metallurgical reference work, and sales ofthese volumes have continued to be steady since theConference.

In the second year of the existence of this Committee, amission, policy, and strategy statement was drafted withregard to the environment. This was accepted by Counciland added to its 'Family of Documents'.

In summary, the Committee's mission is to be therecognized professional forum for mining, minerals,metals, and the environment; its policy is to commit itselfto professionalism and objectiveness towards conservationand the environment; and its strategy is to raise the levelof awareness and responsibility of its members towardsthe environment.

The strategic objective will be pursued through edu-cation and training; in the Journal of The South AficanInstitute of Mining and Metallurgy; by awards (by thesupport of EPPIC awards and the initiation of SAIMMawards); by integration with other forums, organizations,or groups concerned with conservation; by the promotionof public relations; by the creation within the SAIMM,particularly at Branch level, of special-interest groups onthe environment; by liaison on environmental regulationsand protection with other associations, tertiary educationalinstitutions, and government departments; and by beingin a position to take a stand on environmental issues.

Five members of the Committee visited Richards Bayand held discussions with Richards Bay Minerals (RBM),the Zululand Environmental Alliances (ZEAL), the StLucia Action Group (SLAG), and the Natal Parks Boardto gather opinions on the possible mining of titaniumsands in the St Lucia area. One could not but be impressedby the rehabilitation work carried out by RBM on thecurrent lease area, for which the company receivedEPPIC's National Premium Award for integratedenvironmental management in 1989. The question ofwhether mining should be allowed to extend into the StLucia area is a complex one, and the Government'sdecision must await the thorough assessment of theenvironmental impact of this activity required by theMinister of Environment Affairs.

After considering the merits of several worthy can-didates, the Committee put forward New Vaal Colliery asthe Institute's nomination for EPPIC's National PremiumAward in 1991. Members can be proud that this awardwas made to New Vaal Colliery at the WorldEnvironment Day Symposium on 5th June, adding to thesuccesses of RBM mentioned above, and the De Rustopen-cast silica-mining operation of Consol Industries,which won EPPIC's Johannesburg Regional Award lastyear-also on the recommendation of this Committee.

2.7 Special Interest Group-Surface MiningDr G.A Fourie, Chairman

The Organizing Committee, with the assistance ofProfessor AN. Brown, arranged a number of visits to majoropen-cast and strip-mining operations in South Africa. Sitesvisited include Optimum and Duvha, both of which uselarge walking draglines for overburden stripping.


Delegates were briefed on the latest technologicaldevelopments in surface mining techniques, with specialreference to the rehabilitation of mined-out areas.Conservation of the environment is becoming a majorfactor to be considered when surface mines are beingplanned and operated.

The Group is seeking closer co-operation with theSouth African Institute of Quarrying and otherorganizations in an effort to improve its service to themining industry.

It is therefore actively involved in establishingacademic courses at designated technikons and technicalcolleges to facilitate specialist training in surface mining.

2.8 Special Interest Group-Process ControlDr M.H. Moys, Chairman (co-opted)

This group has continued with its visits to plants andresearch institutions where process-control developmentsare of interest

The procedure followed during a visit is generally asfollows. After a start and introduction at about 14:00,several short presentations are made by plant personnel ontopics of relevance to process-control developments onthe plant to be visited. Delegates are then taken throughthe plant in small groups. The afternoon closes with asocial event.

The visit to the Precious Metals Refiners (pty) Ltd inRustenburg at the end of 1990 was poorly attended butgreatly valued by the participants. One result of the poorattendance was a decision that, in future, announcementsof the visits of this Interest Group would be sent to allSAIMM members.

Another visit was to Mintek's Measurement andControl Division. This was an exceptionally well-organized visit Three groups were taken on a tour of theDivision's major projects, viz multi variable control,measurement of the size distribution of ore on conveyorbelts, the use of cyclune flare angle in the control ofgrinding mills, etc.

Two more visits are planned in 1991: one to WesternDeep Levels in July, the other to AECI ProcessComputing in October.

Visits are generally highly valued, and we encourageSAIMM members to take advantage of them.

2.9 Special Interest Group-Computer ApplicationsP. van Schaardenburgh, Chairman

The past year has seen a very low level of seminaractivity. Although this may seem to be disappointing, theCommittee of the SIGCA identified the need forrepositioning and restructuring in order to do justice to thecatalytic process of bridging the gap between the data-processing profession and the customer base to which thisprofession delivers a service.

The Committee decided therefore to concentrate on the

308 SEPTEMBER 1991

following:. restructuring of the Committee, so that full mem-

bers can be recruited only from the mining housesand mining companies, and representatives fromlearned societies and vendor companies may be sec-onded by invitation;. the adoption of a long-term approach in terms of

seminars, colloquia, conferences, and schools, andthe subsequent preparation of a programme;. the inclusion of input from universities and tech-

nikons in the execution of the above programme.

The Committee is negotiating a two-year programme,the fruits of which will become apparent during the courseof 1991.

3. PUBLICATIONS

Portfolio Holder: R.D. BeckKey Performance Areas

The SA/MM. publishes a monthly journal with a balanced content

and of high technical standard as a means ofpromoting technology transfer in all areas of interestto its members, and as a communication medium tokeep its members informed on matters relating to theirprofessional interests;. publishes monographs, the proceedings of internat-

ional symposia and conferences, and otherpublications of a high technical standard on topicsrelated to fields such as underground mining, surfacemining, extractive metallurgy, metals technology, andmaterials science as a means of promoting technologytransfer within South Africa and as a mechanism forthe display of South African skills to an internationalaudience;. enters into reciprocal international agreements for the

advertising and marketing of publications to thefinancial advantage of its members.

Mr Paul White allocated specific responsibilities tomembers of his Journal Committee. This focused atten-tion bore fruit in increased advertising revenue and agreater variety of papers, the latter being in line withefforts to increase interest in the Journal from all mem-bers of the Institute.

The costs of publication increased dramatically. Withthe withdrawal of Mrs Claire Keamey from typesetting,they will be even higher in future.

This led to an evaluation of desk-top publishing (DTP),which indicated that, in the light of escalating publishingcosts, the Institute will derive economic benefits from theuse of such equipment.

If an increased number of books, monographs, or pro-ceedings are published, DTP will contribute significantlyto the funds of the Institute. It is believed that such mate-rial is available within the minerals industry. Other bene-fits of DTP will be: improved quality of diagrams and the


ease with which the layout of the Journal can be changedand controlled. This will be of advantage in the currentdrive to make the Journal more readable.

Council approved the purchase of the necessary equip-ment at its May meeting. The secretaries for the Journaland book publications will, in future, form thePublications Team. Mr Rick Mohring led his BookPublications Committee enthusiastically but struggled forsome time to get volumes in the pipeline into print. Theproblem of authors not meeting deadlines continues todelay publication. Editing to maintain the high technicalstandards expected of the Monograph Series has alsodelayed publication.

Consideration will be given to rapid publishing in theSundry Publication Series in future, while the subjectunder consideration is most topical.

The high cost associated with publication of the IDMCvolume on time lent support to the decision to install DTP.

The change in the fortunes of the minerals industry hasresulted in a reduction in job advertising. The Institute'sNews on the Job Market has suffered in line with this.

Thanks once again to the efforts of the Secretary,Caroline Jansen, a three- to four- month lead time ofpapers was maintained throughout the year. Further thanksare due to the members of the Committee, who activelyshared the workload, and to Peter Smith who, with theSecretary, succeeded in increasing advertising revenuesby more than 40 per cent.

The 1989190 goal of increasing the readability of theJournal through the introduction of more non-researchmaterial has been, and will continue to be, implemented.Thus, the past year has seen articles on innovations intechnology and management, new developments in theindustry, and legal aspects that have an impact on theviability of the industry. Mineral and operational reviewshave also been featured. These articles, together withhigh-calibre research articles that remain the backbone ofthe Journal, have significantly increased its readability forthe general membership.

The financial aspects of the Journal continue tocommand attention. Operational deficits continue toincrease as a result of lower overall revenues andescalating production and overhead costs. Earned revenuesfrom advertising for the year have shown an overall netincrease of some 35 per cent despite a small deficit fromjob advertising, which has been virtually discontinued. Theissue of accounting revenues from exchange rates,exhibitions, grants, and a contribution from membershipfees needs to be addressed if Journal revenues Me to bemeaningful. On the cost side, production costs have insome instances more than doubled. The new desk-toppublishing system that has been purchased should morethan contain these spiralling costs.

Two volumes were completed during the year. Thefirst, containing the proceedings of the International DeepLevel Mining Conference (IDMC), was published beforethe Conference was held in September, and a book on theCorex process has been completed. The latter publicationwas published with the support of Iscor andVoest-Alpine.

Five volumes are in the production stage, and a furthertwo potential volumes are under consideration. Productionschedules have once again had to be extended becausedeadlines have not been met by authors.

The volume of sales of Institute publications wassatisfactory for the year, and the Committee's marketingdrive continues. The storage problems experienced lastyear after the move from Kelvin House have beensatisfactorily resolved. The reorganization of book stockshas enabled the redundant stock position to be reviewed.Redundant stock will be made available to technikons anduniversities.

Caroline Jansen returned as Book PublicationsSecretary during the year, and her valuab1e contribution isappreciated.

The contribution of the organizing committee for theIDMC in getting the proceedings published on time is


gratefully acknowledged.

As can be seen from the following reports, theBranches of the Institute had another active year. BranchChairmen and their committees must be congratulated ontheir efforts to arrange stimulating meetings and outingsfor their branches.

The Johannesburg and Pretoria Branches havefollowed the lead of the Western Cape and Vaal TriangleBranches by holding functions aimed at students.

A new branch was started in the north-westernTransvaal under the enthusiastic leadership of Dr LarryCramer. The inaugural meeting, which was attended bythe Chairman of the Regional Development Committeeand the President Elect, was well supported, and bodeswell for future activities in the interest of SAIMM mem-bers in the region.

Discussions were held with the Association of MineManagers of South Africa on possible areas of closer co-operation. Good progress was made during the year.

Interaction with other bodies active in the mining andmetallurgical industries continues.

The Johannesburg Branch of the Institute has once

310 SEPTEMBER 1991

again had a very busy and successful year. As mentionedin the previous Annual Report, the Institute vacated itsoffices in Kelvin House and moved to new premises inCape Towers. The loss of facilities presented difficultiesfor the Branch with respect to venues for generalmeetings. The Branch is now required to hire a venue atcommercial rates, and has to rely on sponsors for itsevents. In this regard, the Committee, on behalf of all itsmembers, wishes to express its gratitude to all thosecompanies and organizations that have sponsored theBranch's general meetings held in the evenings, andhelped to make them a success.

The concept of general meetings that are held in theevenings every two or three months and at which multi-disciplinary presentations are given on projects or topicsof general interest has once again proved successful. Thissuccess has been manifested by attendances of up to 250people on the various occasions.

The following general meetings were held:

July 1990(AGM):VenetiaDiamoodProject (McB. Ainsley)November1990:RichardsBayMinerals (McRD. Macpherson)February 1991:Sasol/SecundaCollieries(McC,J. Cloete)May 1991:SouthDeepProject (McW.A. Nairn).

The Committee thanks tke organizations involved forsponsoring the cocktail parties after each of the meetings.These events provide an important opportunity formembers and their guests to interact on a social level.

Fifty-year Membership Awards were presented to thefollowing members during the year: V.C. Barnes, A.H.H.Davison, E.T. Dunstan (posthumously), A.RC. Fowler,E. Margo, E.R Rudolph, and I.S. van Eyssen.

A students' evening was held on 11th September, 1990at which four students (two from the University of theWitwatersrand and two from the Witwatersrand Tech-nikon) gave presentations on their final-year projects.Attendance was by invitation, and the presentations werefollowed by a cocktail party sponsored by theJohannesburg Branch. Approximately 100 peopleattended, and the evening was most successful. It isintended that this should be an annual event to furtherstrengthen the links between tertiary educationinstitutions, the SAIMM, and industry.

Approximately 100 people attended an afternoon visitto the Johannesburg Stock Exchange in July 1990. A pre-sentation on the general workings of the JSE, with anexplanation of the Option and Futures Market, wasarranged by Fergusson Brothers, which also sponsored acocktail party.

A two-day visit to Keeley Granite, Buffalo Fluorspar,and Rooiberg, which had been arranged for August 1990,was cancelled owing to lack of support. Because of thelow levels of interest displayed in the past, the Committeedoes not intend to arrange further two-day visits in thefore- seeable future.

An excursion to Valindaba, kindly arranged by theAtomic Energy Corporation, took place on 21st March,1991. The 34 people who attended were provided with an


opportunity to view a wide and interesting variety oftechnologies.

Another technical visit was arranged to the RandRefinery. This always proves popular, and is well sup-ported. The visit took place on 6th June, 1991, and wasfully subscribed.

The Branch wishes to reiterate its thanks to all thoseindividuals and organizations who gave of their time andprovided sponsorship to make the Branch functions thesuccess they were. Also, thanks are due to the SAIMMSecretariat for the service and support it provided, and theinterest it shows in the activities of the Branch.

The Annual General Meeting was held at theAllanridge Mines Club on 25th July, 1990. It was well .attended (53 persons) by members and guests. The guestspeaker was Dr G. Hughes of the Natal Parks Board. Hisaddress centred on the activities of the Board, withparticular reference to its relationships with the peopleliving in the areas under its control. He also spoke aboutthe various fund-raising operations and the Parks Board'sviews on the mining of beach sands on the eastern seashores.

The Branch Committee meets on a regular bi-monthlybasis. It endeavours to increase the activities of the Branchby arranging short technical visits and addresses by guestspeakers at general meetings. These addresses cover arange of topical subjects of interest to members andguests.

Two technical visits took place during the year. Thefirst was to New Vaal Colliery on 14th November, 1990.A total of 18 members attended. Mr Dick Watts, the MineManager, arranged a very interesting visit to the open pitand discussed the problems involved in the mining of coalseams that had been previously worked from undergroundworkings. The scale of the operations and the minimalnum~r of people involved was impressive. An excellentbraai lunch on the banks of the Vaal River was enjoyed byall. ,

The second visit, attended by 16 members, was to HJ.Jool Gold Mine on 23rd January, 1991. The group wasmet by Mr Chris Naude, the General Manager, who gave apresentation on the operation of the mine. The delegateswere impressed by the safety record and efficiency of themine. The group was taken underground to visit themechanized development ends and, on their return tosurface, went to the gold plant and single quarters.

The annual excursion, which took place on 17th and18th June, 1991, consisted of a visit to KoffiefonteinDiamond Mine, and was attended by 19 members.

Mr Frik Blaauw, the General Manager, introduced thegroup to the guides and gave a talk on the history andoperations of the mine. A tour of both surface andunderground activities took place on the Friday. A pubnight was organized in the evening at which membersenjoyed the company of the local community. Saturdaywas spent playing golf by the more energetic members.

Two general meetings were held during the year. Thefirst was held in the;Free State Geduld Mine canteen on23rd October, 1990, where Mr Bill Odendaal, the Mayorof Welkom, gave a presentation on 'Changes to LocalGovernment in the New South Africa-Proposals for theOFS Goldfields'. He explained the implications of thevarious proposed models in the Thornhill Report and theeffect these would have on local communities.

The second general meeting was held in the FreegoldNorth Region canteen on 24th May, 1991. The guestspeaker was Mr Gerald Gardner, Manager: GroupTaxation Services of Johannesburg ConsolidatedInvestments. Mr Gardner, who is the Chairman of theChamber of Mines GSTN AT working group, and is alsoa member of the advisory body on VAT to the Minister,gave a talk on 'Effects of VAT on the Mining Industry'.He explained the workings of the new system, andsuggested how the mines could effect savings in workingcosts. He went on to illustrate the various implications ofthe imposition of VAT on the man-in-the-street The talkwas attended by 62 members and visitors.

Membership fluctuated during the year owing to themovement of members. It currently stands at 127.

4.2.3 Pretoria Branch

The Pretoria Branch had a successful year during whicha number of meetings were held. The Committeefunctioned well, and the organization of the various eventswent smoothly because of the enthusiastic support of allthe Committee members. Four Committee meetings wereheld during the year and were well attended.

The Annual General Meeting of the Branch was heldon 30th July, 1990 at the Sports Centre of the Universityof Pretorla, and was attended by some 50 people. Mr H.G.Mosenthal addressed the meeting on his impressions ofthe Far East and what could be learnt from it. He alsopresented Dr R.F.J. Teichmann with his 50-yearMembership Badge. In his reply Dr Teichmann mentionedsome of the highlights of his distinguished career. Thiswas followed by a cocktail party sponsored by the BarlowTractor Company. .

The Branch also visited the BMW assembly plant on15th November, 1990. This was a most interesting visit,which, thanks to the hospitality of the hosts, proved to bequite a soCial event. The Committee was pleased that somany of the senior members of the Branch attended this


function, and hopes to attract them to similar events in thefuture.

The Branch, together with the Department of MaterialsScience and Metallurgical Engineering of the Unive~sityof Pretoria, also initiated a Metallurgical Forum duringthe year. The aim of this forum is to stimulate interest inmetallurgy and also to bring students into contact withsenior members of the profession. The Committee wasindeed fortunate to fmd excellent speakers for the initialmeetings and hopes to continue in this vein.

Mc Jack Hewitt, Group Manager: Research and De-velopment of Middelburg Steel and Alloys, addressed themeeting on 20th February, 1990 on 'Innovations in theAnnealing of Stainless Steels'. Dr Brian Loveday, Con-sulting Metallurgist of Anglo American Corporation,addressed a meeting on 20th March, 1990 on 'Design andControl of Milling Circuits'. Mc Peter Bailey, ConsultingMetallurgist of Gengold, gave a talk on 'The Operation ofRun of Mine Mills' on 17th April, 1990. Mr NoelPeverett, Assistant Consulting Metallurgist of GoldFields, gave a talk on 'Recent Developments in ThickenerTechnology' on 15th May, 1990. Three more forums areplanned for the rest of the year.

The Committee is satisfied with attendance at theevents hosted by the Branch, but would like to attractmore of the senior members on a more regular basis. Weare encouraged by the involvement of students from theDepartments of Mining Engineering and of MaterialsScience and Metallurgical Engineering of the Universityin the activities of the Branch, and see this as a means tointroduce them to the profession and the Institute.

4.2.4 Vaal Triangle Branch

Prof. M.D. Brayshaw, ChairmanK.R.E. Beard M.A.L. van der WaltNJ. Fourie .D. Wilson*JJ. Nell J. Urrutia*Resigned during the year

The Annual General Meeting of the Branch took placeon Tuesday, 19th June, 1990 at the US KO Club inVereeniging. The meeting featured the immediate past-President, Dr Oskar Steffen, who outlined his past year asPresident of SAIMM. The guest speaker was Dr PhillipLloyd of !PC who spoke in his usual entertaining mannerabout pollution, and gave his own particular interpretationof a long-standing South African problem.

The Dr Arnold Mol function took place on Tuesday,14th August, 1990 at the Iscor Recreation Club. Themeeting was originated by our Branch of the SAIMM(through Mc Kenny Beard), but was co-hosted and co-organized by local branches of the South African Instituteof Chemical Engineers (SAIChE), the South AfricanInstitution of Mechanical Engineers (SAIMechE), and theSouth African Institute of Electrical Engineers (SAIEE).

The event was a great success. Approximately 250people from the four engineering institutions attended the

312 SEPTEMBER 1991

meeting with their wives and friends. Dc Mol spoke aboutmotivating people in the work situation and gave manyhelpful, possibly controversial, but certainly challenging,approaches for managers to motivate the people in theircharge. Dc Mol's talk was very well received, and a livelydiscussion in the form of questions took place during histalk and afterwards.

The function was a reasonable financial success, thefour institutions sharing the profits.

The Branch noted with grief the passing of a well-known and renowned member of the Institute for 50years, Mc D.D. McWilliam.

A joint meeting with the Institute of Refractories tookplace on 18th October, 1990 at the Jan Smuts Airport SunHotel. Dr MJ.U.T. van Wijngaarden, the guest speaker,gave a presentation entitled 'Interaction of Metallurgy andRefractories in Ladle Furnaces'. The meeting was verywell attended and was successful.

The second scholars' evening for Metallurgy in theVaal Triangle, which was held on Tuesday, 23rd April,was co-hosted with the Vaal Triangle Technikon at theirCareers 2000 Exhibition during the week of 22nd to 26thApril.

The evening featured two videos on metallurgy, as wellas the same guest speakers who gave entertainingpresentations at the flfst meeting of this kind in the VaalTriangle in 1990: Professor David Horsfall and ProfessorGert Pienaar.

The evening was organized in conjunction with theTED, DET, Iscor, and the Vaal Triangle Technikon. Itshould have had a good attendance from Std 9 and 10scholars studying maths and science at these levels inboth educational departments. The advertising amongscholars was left to the two representatives from the TEDand DET. The evening was again a large success, but theaudience was almost exclusively black. This was becausewhite scholars had not been reached by the advertisingcampaign. A great deal of interest was shown by the blackscholars, and we can only hope that some of the attendeeswill be attracted into our profession.

Iscor sponsored the refreshments, and the scholars hadthe opportunity to speak to representatives of the mininghouses who were on duty at their stands at the Careers2000 Exhibition.

As in previous years, the level of interest shown in theBranch's activities by local members was disappointing.The biggest single employer of metallurgical personnel inthe area is Iscor. This situation is enhanced by the declinein the activities of the other major metallurgical player inthe region (USKO), following its recent poor financialperformance. Many of the senior metallurgists workingfor USKO and who were, until recently, active in theBranch's activities, have had to discontinue theirinvolvement owing to extreme work pressures. This hasbeen very sad for the region, and has taken its toll of localinterest .

A meeting with Iscor personnel was held to promote


Branch activities among the metallurgists working forthis, the largest company in the area. The meeting wasfairly successful, but the harvest of interest can be gaugedonly by the extent to which personnel from theorganization will participate in the Branch's activitiesduring the coming year.

The Branch kept visits to metallurgical companiesduring workings hours to an absolute minimum-in factthere have been no such visits-owing to the lack ofresponse in previous years to this type of activity.

The decision to relocate the entire Engineering Facultyof the Potchefstroom University has constituted a furtherblow, and will limit future growth of interest in the area.

4.2.5 Western Cape BranchProf. C.T. O'Connor, Chairman

U. Cilliers Dr RD. KnutsenProf. F.LD. Cloete L LorenzenDc J.-P. Franzidis Prof. J.SJ. van Deventer

The Committee held seven meetings during the pastyear and continued to focus its activities on creating anawareness of the minerals industry in the region. Inparticular, these activities involved mainly the Departmentof Chemical Engineering at the University of Cape Town(UCT) and the Department of Metallurgical Engineeringat the University of Stellenbosch (US). The Committeealso welcomed, in particular, the important contributionmade this year by Dr RD. Knutsen frol}l the Departmentof Materials Engineering at UCT.

The Ninth Annual US/UCT Minerals ProcessingSymposium was held at the Van Riebeeck Hotel inGordon's Bay on 3rd August, 1990, and was attended by99 delegates. The Branch is grateful to SA Cyanamid,NCP, Simon Carves (Africa), and the SAIMM forsponsoring this event. The conference was preceded onthe evening of 2nd August by the Annual GeneralMeeting of the Branch, followed by the Annual Banquet.We were privileged to have the President of the Institute,Dc O.KH. Steffen, as guest speaker.

A Corrosion Seminar was held on 22nd March, 1991 atUCT. This was a highly successful technical meeting andwas attended by 80 people. The main speaker was DrStephen Lennon, Scientific Investigation Manager,ESKOM.

One of the important functions of the Branch is togenerate interest in careers in the mining industry amongscholars in the greater Western Cape region. This year'sSchools' Day was held on 22nd April, 1991. As usual,simultaneous programmes were offered at both UCT andUS. Once again, there was an enthusiastic response to theinvitation, 126 pupils from 26 schools attending the UCTprogramme, and 84 pupils from 20 schools the Stellen-bosch event.

During the 1991 mid-year university vacation, theBranch is organizing, once again, a tour for MineralsProcessing undergraduates from both universities. This

year's tour will be led by Mc Jan Cilliers, assisted by Mc J.Tucker, a Senior Technical Officer associated with theWestern Cape Minerals Processing Facility. This year'svisit will be to northern and eastern Transvaal mines.

The lOth Annual Minerals Processing Colloquium willbe held at Gordon' s Bay on 2nd and 3rd August, 1991.Because of the success of this event over the past 10years, the Branch has decided to expand the Colloquiumto a two-day meeting. At the same time, papers are beingcalled for from persons other than researchers at the twolocal universities, although the emphasis remains that ofgiving research students at the universities the opportunityof presenting their current research findings to a criticalaudience. So far, there has been an overwhelmingresponse to the call for papers, which will necessitate afair number of posters. There is every indication that thisconference will be an outstanding success. The plenarylecturer w.illbe Professor Ted Woodburn of the Universityof Manchester Institute of Science and Technology(UMIST).

This year the Branch was requested by Council toarrange for the presentation of 50-year MembershipAwards to five members of the Institute currently residingin our region, namely Messrs C.H. Coxton, O. Deane,E.RC. O'Connor, J.S. van Zyl, and O. Weiss. Specialarrangements were made to present these medals toMessrs Deane, O'Connor, and Weiss. The othergentlemen have agreed to attend this year's AnnualDinner to receive their medals from the President of theInstitute. All the members of the Committee wereinvolved in one or other of the presentations to the fIrStgroup of medallists, and all agreed that these were trulymemorable events. The gold medallists were unanimousin their praise and gratitude to the Institute for the medals,and the Branch congratulates Council on the introductionof these awards.

The Branch thanks the Council of the SAIMM for theexcellent support it has enjoyed over the past year.Although the Branch is far removed from the heart of themining industry, we believe that, through its teaching andresearch functions, it is able to contribute significantly tothe activities of the Institute.

The year has not been a good one for the Branch, and, atone stage, the future of the Branch and its continued func-tioning were discussed. However, the outgoing Committeehas placed the Branch on a sound footing, and it will con-tinue to serve the aims of the SAIMM in the area.


Mr Tom Schmoll, a member of the Committee for anumber of years, passed away in May 1991. He was serv-ing as Branch Chairman at the time of his death, havingtaken over from Mr J.A.D. Britz in April following theresignation of Mr Britz from the Branch Committee.

On 25th September, 1990, 17 members and guestsattended a general meeting at Springbok Recreation Club.Two papers were presented- 'Combating Corrosion withStainless Steel' by Dr 1. Fourie, and 'Review ofKleinkopje Colliery Spiral Plant' by P. Henry.Goedehoop Colliery hosted the meeting.

A total of 22 members and guests attended a visit to theStainless Division of Middelburg Steel and Alloys, duringwhich the entire stainless-steel process from 'melting' tofinished product was demonstrated. The general meetingplanned for 22nd May, 1991 at Bank Colliery was can-celled because of the death of Mr Schmoll.

5.1.1 Controlling ExecutiveProfessor AN. Brown was inaugurated as President of

the AS&TS in November 1990. Relocation from KelvinHouse to the new site at Observatory was completed andthe office accommodation and meeting rooms wererenovated. Most of the available accommodation isoccupied and the meeting rooms are being well used. Amodest plan for development and improvement of the siteis being drawn up, and will be implemented progressivelyas funds become available. However, the presenteconomic climate is not very favourable for the raising offunds.

The AS&TS continued to experience difficulty with itsfinances but now that renovations are complete and all theSocieties are established and settled, every effort is beingmade to run the AS&TS profitably.

5.1.2 Science and TechnologyThe Learned Society Function was the subject of con-

siderable debate during the year. Activities of theCommittee for Science and Technology form the corefunction. It is perhaps understandable that these activitiesreceived less attention and tended to be somewhatneglected in the relocation to Observatory. However,serious consideration needs to be given to the value andusefulness of such activities, particularly in the presentstrained economic climate. The matter has not yet beensatisfactorily resolved.

The AS&TS played a role as one of the organizers ofthe World Environment Day Symposium, which was heldat Mintek on 5th June, 1991. The theme was 'Soil'. At-tendance was smaller than in previous years. The SAIMMnominee for the EPPIC Annual Award was successful.The management of New Vaal Colliery received thisaward in recognition of its work in environmentalplanning, control, and rehabilitation under difficultconditions.

Contact with the PROTEC programme wasmaintained, as was the connection with AFROTECH. Thelatter is heavily dependent on funding from the privatesector, and its activities are currently restricted by limitedfinances.

The AS&TS National Award was made to the Iscorteam for its ingenuity and perseverance in bringing thenew Corex steelmaking process to a successfulconclusion. It is the first plant in the world to have doneso. The SAIMM nominated Iscor for this Award.

During the year under review, the Engineering Councilof South Africa (ECSA) came into being when Parliamentpassed the Engineering Profession of South Africa Act(Act No. 114 of 1990). On 18th April, 1991, the functionsof the South African Council for Professional Engineers(SACPE) and the three Boards of Control (forProfessional Technologists, Registered CertificatedEngineers, and Engineering Technicians) were taken overby ECSA.

This is a significant milestone in that a single Councilwill now be responsible for the following importantfunctions with respect to the whole engineeringprofession:

. setting the standards for registration. registering applicants who comply with the standards. accrediting qualifications. prescribing and enforcing a code of conduct. publishing a tariff of recommended fees for consulting

work. proposing reserved work. recognizing engineering institutes.

Depending on the level of education and training, asuccessful applicant can be registered in one of thecategories listed below. The names and abbreviationsreserved for persons registered by ECSA are:

The functions of the PAC Mining and PAC MetallurgyCommittees, whose members are nominated by theInstitute, remain as they were under SACPE. During thepast year, these Committees continued their importantwork of screening the qualifications and practicalexperience of applicants for registration as ProfessionalEngineers. Several training programmes for engineers-in-training, which had been submitted by local mining and

metallurgical organizations, were screened by theCommittees. Assistance continues to be provided bynominees of the Institute in the accreditation of coursesoffered by universities and technikons in the disciplines ofmining and metallurgy.

S.3 The South African EngineeringAssociation (SAVI)

Representative RD. BeckAlternate Dc O.K.H. Steffen

After a long series of discussions between represen-tatives of the professional institutes and vocational groups,a draft constitution for the South African EngineeringAssociation (SAVI) was drawn up, and the Associationwas formed in May 1989. A representative of the SAIMMwas party to these discussions, and Council debated issuesraised on a number of occasions. The concerns raised bythe Institute were not wholly addressed.

The SAIMM supported the aims of SAVI, which aredefined in the Association's constitution as follows:(a) to advance the status and image of engineering;(b) to further co-operation, communication and unity

among the engineering profession;(c) to strive for improved engineering education and

training, and to promote careers in engineering for allSouth Africans;

(d) to promote liaison with other national, regional andlocal authorities, and the public;

(e) to advise and act on matters of policy and legislationthat affect engineering as a whole at national level.

The Council could not recommend joining SAVI for thefollowing reasons..SA VI has an agreement that membership of SA VI

requires compulsory membership of the Society forProfessional Engineers (SPE). The principle that joiningof vocational groups must be individually voluntary isstrongly upheld by the SAIMM. In addition, themajority of the objectives of SPE are already covered bythe Institute..The weighted vote based on members of the Instituteswas not acceptable to the SAIMM..Other minor problem areas, including the budget, werecause for concern.

In view of the important initiatives being taken by SAVIin the field of education, the SAIMM felt that the Instituteshould accept SAVI's invitation to attend meetings of theSAVI Council and negotiate changes that the SAIMM feltwere necessary if it was to join SAVI.

The issue of compulsory membership of SPE was de-linked from SAVI, and membership of that vocationalgroup is now a separate issue. A new weighted vote wasnegotiated and accepted by SA VI and the SAIMMCouncil.

In February 1991, the SAIMM Council decided that theSAIMM would join SAVI after the necessary changes had


been made to the SAVI constitution. These changes werebeing made at the time of the writing of this report.

The SAIMM has expressed concern at the structures inwhich SAVI operates in relation to member institutes andvocational groups, but believes this issue will best bedealt with when it is a full member of SAVI.

The following issues were dealt with by SAVI duringthe year.

EducationIn response to the concern about the decline in the

numbers of people entering the engineering professionand the conviction that a strong engineering profession isrequired for the future development of South Africa,SAVI developed the concept of the National Foundationfor Technological Development (NFTD). This conceptwas refined in negotiations with major employer bodies,the Government, and industry.

The initiative was submitted to the Economic AdvisoryCommittee (EAC) of the State President in September1990. While receiving overall support, the document wasrejected on the grounds of the concern expressed by theEAC that it would involve the establishment of yetanother bureaucracy. SAVI was requested to rethink itsdesire to establish a separate body and to identify ways ofinter- acting with an existing government body.

To this end, the newly structured Foundation of Res-earch Development (FRD) was identified as being asuitable vehicle. Discussions were held with the FRD andthe basis for a partnership was decided upon. The detailswere submitted to the EAC in November 1990. Thedocument was accepted, with one slight modification, inthe hope that the EAC would retommend to its executivesthat the concepts were of sufficient importance to receivethe highest attention within Government.

The major objectives of the education initiative are tocreate closer links between technikons and universities inan attempt to optimize resources, provide for adequatestaff interchange and, finally, to ensure a sufficient outputof suitably qualified graduates and diplomates.Furthermore, it is seen to be vitally important thatcognizance should be taken of the important assistancethat tertiary engineering educational institutions can givethe country by providing the necessary man-power skillsfor uplifting the economy.

A fifteen-man board comprising the FRD, industry,and SAVI has been formed to act as a Controlling Boardto carry these objectives forward. The minerals industry isrepresented by Mr AH. Munro, FSAIMM, acting for theChamber of Mines.

Technology StrategyThe document on Technology Strategy from the

Department of Trade and Industry and the draft StrategicDocument on Technology published by the ANC wereexamined and commented on by SAVI.

316 SEPTEMBER 1991

Unification of the Engineering ProfessionSAVI continued to express concern that the South

African Institution of Chemical Engineers (whichwithdrew from SA VI over the same issues as theSAIMM) and the SAIMM were not members of SAVI.With the changes already reported, both have indicatedthat they will join SAVI.

SAVI Think-tankOn Saturday, 26th January, 1991, members of the

SAVI Council and Presidents of the Institutions wereinvited to participate in a one-day SAVI Think-tank. Thecurrent structure of SAVI was discussed, as well as therole of the vocational groups, issues relating to theadministration and financing of SAVI, and other projectsthat were deemed to be important for the future well-being of the engineering profession in the country. It wasconcluded that SAVI should take an active lead in thepromotion of technology, in forging links withinternational engineering organizations, and in setting upa major campaign to try to inform the public of theimportance of technology.

Relationship with ECSAAn important feature of the deliberations of the SAVI

Think-tank was the relationship with the new EngineeringCouncil of South Africa (ECSA). While it was recognizedthat each body has a specific role to play in terms of theconstituency to which it must report, it was thought thatthere are a number of areas in which a combined approachmight be more beneficial. It was unanimously agreed thatco-operation would only strengthen the engineeringprofession and, in particular, could lead to rationalizationand reduced costs. Both parties committed themselves tothis goal.

Relationship with the Scientific CommunityOne of the areas of concern expressed by the SAIMM

has been about the future of the AS&TS as a learnedsociety. The strength of SAVI has been seen as a potentialthreat to AS&TS. SAVI has recognized the importance ofcloser ties between the engineering and scientificprofessions. The SAIMM has expressed its convictionthat the AS&TS should exert itself as the key player inforging these links.

In conclusion, the arena provided by SAVI to enablerepresentatives of the various fields in the engineeringprofessions to meet, discuss, and take up issues ofcommon interest is seen as an exciting development forengineering. The SAIMM is actively contributing to thisdevelopment.

Following the previous year's activities, it wasnecessary for the Committee to meet only as and whenrequired. The new Engineering Profession of South AfricaAct, 1990 (Act No. 114 of 1990) was promulgated in1991. This document has been studied carefully by theCommittee, and a summary of the 'Role and Implicationsof the New Act' will be published in the Journal shortly.

5.5 The Association of South AfricanRegistered Engineering Technicians (ASARET)

Representative D. WilsonAlternate Dr J. Lurie

The historic inaugural meeting of ASARET took placeon 18th September, 1990 at Megawatt Park. ASARETwas constituted in order to fulfil the requirements for thevocational body to represent the interests of engineeringtechnicians. As such, it is a society of individual members,as opposed to an affiliation of societies (as was ASRET,which it replaces). The latter organization will bedisbanded in due course.

SAIMM has become a patron member of ASARET inorder to ensure a continuing input from the learnedsociety. Dr J. Lurie was elected to the Council ofASARET and also appointed as the Council representativeon the SPE/SA VI Education Committee.

Approximately 600 applications (representing anumber of engineering disciplines, including mining andm~llurgy) were received for individual membership inresponse to the first circular letter to registeredengineering technicians.

An initiative has commenced whereby technicians inthe mining and metallurgical fields will be ertcouraged toregister with the Engineering Council of South Africa(ECSA) and to join ASARET.

5.6 South African Association of RegistrableEngineering Technologists (SAARET)

Representative Dr J. Lurie

The Executive Committee and Education and Trainingand Publicity Sub-committees held monthly meetingsduring the period.

A highly successful Autumn School, organized jointlyby SAARET and the Student Mechanical EngineersAssociation, was held during April 1991 at the TechnikonWitwatersrand.

The SAARET award for the most outstanding Masterdiploma student in an engineering discipline was awardedto Mr A. Oosthuizen, a Mechanical Engineering student ofthe Vaal Triangle Technikon.

The future format in terms of duration, experientialtraining, and investigative projects for the formaleducational qualification of the technologist at technikonswas considered widely in the engineering world and alsoby the SAARET Education and Training Committee. Sofar no consensus has been reached.

Profiles of mining and metallurgical technicians and

technologists were submitted by working groups. That forthe chemical engineering technician is complete, but thatfor the technologist is still being considered.

5.7 Engineers' Liaison Committee

Representative Prof. AN. Brown

Mr W.F. Cronje was re-elected Chairman, and theCommittee met under his leadership. The Hendrik van derBijl Memorial Lecture is usually presented in May, but the29th Lecture will be presented in September 1991 by MrGert van der Veer, Chief Executive of SA Airways. TheAnnual Social Function in November was to be held at theCSIR's new wind tunnel, but unfortunately had to becancelled.

5.8 Programme for Technological Careers (PROTEC)The SAIMM continued to support PROTEC by way of

a grant PROTEC provides support for black students inhigh schools, and has a number of branches throughoutSouth Africa, each of which is subsidized by localindustry. The number of PROTEC students grew from4166 to 6098 in 1990/91. The pass rate for the 1990matriculants was 75 per cent, of whom 39 per centobtained exemption (university entrance) in maths andscience.

The above statistics compare very favourably with thenational figures for black students. This was achieveddespite the ongoing disruption of life in blackcommunities and dangerous conditions for staff. Saturdayclasses were offered at most branches to assist students incatching up on lost time. In some cases industry helpedwith laboratory facilities and visits.

More than half of the PROTEC matriculants have takenup careers in engineering and science.

5.9 Phoenix National CommitteeRepresentative Dr B.K. LovedayAlternate Dr RH. Eric

The Phoenix Fund is administered by the SAIMM, anddaily activities and projects are carried out by staff in theEducational Department of the Chamber of Mines ofSouth Mrica (COM). During the early part of 1990, theEducation Advisory Committee of the CaM, whichincludes education specialists drawn from individualmining groups, examined the country's education systemand formulated an overall education policy for the miningindustry.

This policy spells out the Chamber's standpoint on therequirements of an adequate system. The CaM'sEducation Mission is:

. to be actively involved in the development of a relevant

and legitimate national education system, which willencourage optimum economic growth and ensure anoptimum flow of appropriately educated persons intoindustry, and the mining industry in particular.


After the formulation of the education policy, itbecame clear that the promotion of careers in the miningindustry and direct recruiting into the industry was amining-group matter. Consequently, during the latter partof 1990, liaison with schools and other careers-relatedtypes of activities were discontinued. Cost pressures alsoencouraged rationalization and the focusing of activitiesand resources. This resulted in the rationalization of allthe education activities of the CaM into one EducationDepartment. This Department now concentrates onactivities such as the Phoenix programme, Bursaries,Tertiary Education, Support Programmes, and EducationPolicy, as well as advice, liaison with other educationstakeholders, promotion of education policies, and generaleducation administration.

Following the rationalization of all the educationactivities, Mr Demmer was appointed to manage theEducation Department, and to report to the Chamber'sGeneral Manager, Education Services. During January1991, Mc K. McCarogher took control of all aspects of thePhoenix programme, with two members of staff to assisthim with daily activities. Secretarial and administrativeback-up is provided by staff in the Chamber's EducationDepartment.

In consultation with the mining groups, a major thrustof new activities was planned under the expansion of theprogramme. Expansion is aimed primarily at physicalscience teachers and physical science lecturers at theblack colleges of education.

The CaM is the major financial sponsor of theprogramme, which is jointly administered by the Chamberand the SAIMM.

The main goals of the programme for 1990/91 arelisted below:. to provide in-service training and support for science

teacher/educators (lecturers) at colleges of education ona national basis;. to develop and implement science resource material that

relates mining and minerals processing to concepts inthe science syllabus for science teachers; this willinclude the optional science topics on manganese andcopper and on two packages on gold and coal which arecurrently being developed;. to influence education departments and planners of

syllabi and curricula to include a better representationof the minerals industry in new science and geographysyllabi;. to participate in the debate on the formulation of an

education policy for school science in South Africa.

During January 1991, an extensive one-weekworkshop, the third of its kind, was conducted inconjunction with the University of the Witwatersrand for75 college lecturers from black colleges of education. Theblack colleges of education train the majority of

318 SEPTEMBER 1991

mathematics and physical science/general scienceteachers in South Africa. The content of the workshopactivity was designed to upgrade the academic skills ofthese teacher/educators (science lecturers) in bothchemistry and physics. The workshops addressedscience/technology/society issues that are in the newcollege of education syllabi. In consultation with thecollege lecturers, several workshops have been plannedfrom July 1991 to July 1992. These will focus on up-grading their academic and practical skills.

The optional science topics resource packages on thechemistry of copper and manganese were completed in1990. These packages have been extensively introducedinto schools. In the second quarter of 1991, Phoenix staffconducted 24 one-day courses for science teachers fromTransvaal schools. In one six-week period, 580 scienceteachers attended these courses in Pretoria.

An additional two packages are being developed (andtrial-tested in the classroom) on the chemistry of gold andcoal. The fIrst drafts of these packages should be complet-ed at the end of 1991; trial-testing in the classroom willbegin during the early part of 1992. These packages willbe tested extensively in schools before they are printed infinal draft form.

This type of science material, which relates mining andmineral-processing techniques to the school science syl-labus, has been extremely well received by science teach-ers throughout South Africa. It forms part of an ongoingprocess to make science in the school classroom more rel-evant to its applications in everyday life. Such packagesare following trends in other areas in the world where thistype of material is making science and technology relevantto its daily usage.

Staff on the Phoenix programme have been closelyinvolved with a project team working under the guidanceof the School of Science Education at the University of theWitwatersrand to produce guides for science teachersfrom Std 2 to Std 10. The fIrst science teachers' guide (Std5) was completed in July 1991; it will be launched at theNational Science Teachers' Convention in Cape Town.The authors of these science teachers' guides are currentlynegotiating with an international publisher to produce suf-ficient copies for all science teachers throughout SouthAfrica.

The Phoenix Programme has continued to maintaincontact and liaison with other organizations, both formaland informal, whose primary aim is to promote scienceeducation in schools and to encourage scholars to pursuecareers in engineering, technology, and the earth sciences.The CaM and the SAIMM are extremely grateful for thefinancial support received from the following companiesand organizations during 1990: AECI, Mintek, Envirotech,Ferro Alloy Producers' Association, Haggie Rand, Iscor,Rio Tinto South Africa, and Sasol.


5.10 South African National Councilon Tunnelling (SANCOT)

Representative J.A. CruiseAlternate Prof. H.R. Phillips

Civil-engineering tunnelling activities were again low-key during the year under review, two major contractsbeing undertaken by Umgeni Water and the JohannesburgCity Council. Contracts were awarded on the long-awaitedLesotho Highlands Water Project, and tunnelling isexpected to commence later this year.

SANCOT held four informal talks during the year, andthe annual seminar held in November was attended by 190delegates. Twelve papers were presented under the title'Excavate and Support', the opening address being givenby the Minister of Environmental Affairs and of WaterAffairs, Mr G.J. Kotze, MP, and the keynote address byMr Colin Kirkland, President of the InternationalTunnelling Association.

SANCOT continues to take an active role in the affairsof the International Tunnelling Association, and wasrepresented at the General Assembly, which was held inChengdu, China.

The SAIMM is represented on the ExecutiveCommittee of SANCOT, its representative being theHonorary Treasurer.

5.11 The Environmental Planning ProfessionsInterdisciplinary Committee (EPPIC)

Representative J.S. FreerAlternate C.B. Roper

SAIMM has been a constituent member of EPPIC formany years.

Since the promulgation of the Environmental Conser-vation Act (Act No. 73) in June 1989, EPPIC's role hasbecome increasingly important. EPPIC's perception of thefunction it sees for itself in terms of its Strategic Plan is asan intermediary between Central Government and theprofessions and professionals.

The status of EPPIC has been augmented by theapproach made by the Council for the Environment todisseminate the philosophy of Integrated EnvironmentalManagement (IEM) throughout South Africa via itsconstituent Institutes and EPPIC's Regional Groups.

!EM is a systematic approach to ensure the stiucturedinclusion of environmental considerations in decision-making at all stages of the development process.

EPPIC has representation on the Environmental ImpactAssessment Sub-Committee of the Committee forEnvironmental Management under the EnvironmentalConservation Act, and presented its views on its futurerole to a Committee of the President's Councilinvestigating a National Environmental ManagementSystem. EPPIC is increasingly being requested by theDepanment of Environmental Affairs to comment on draft

documents.The Council for the Environment has suggested that

EPPIC should request its constituent Institutes to developproject-specific procedures that incorporate IEMprinciples and to let the Council know (through EPPIC) ofany problems they or their members are experiencing inthe implementation of !EM. Any contribution would bewelcomed, and should be addressed to the SAIMM forsubmission to EPPIC.

EPPIC is currently re-surveying the availability ofenvironmental education at tertiary level. A report on theresults of this survey will be available in due course.

EPPIC recognizes sound environmental planning andmanagement through its National and Regional Awards,which are presented at the World Environment Day Sym-posium in which it participates each year. This year theSAIMM was again successful with its nomination. NewVaal Colliery received EPPIC's National Premium Awardat the Symposium held on 5th June, 1991.

In May, EPPIC held the flfst of what it intends willbecome a series of prestigious annual environmentalconferences. The theme this year was that important andscarce resource in our country-water-and how it shouldbe managed for sustainable use. The conference wasopened by Dr Louw Alberts, Chairman of the CSIR. Some150 delegates attended. The standard of papers wasexcellent, covering a wide range of aspects of water,including the potential for its pollution from miningoperations.

EPPIC has prepared and makes available to itsmembers various publications. Currently available are theGuidelines for Public Participation in EnvironmentalPlanning and Decision-making and a summary of theimplications of the Environmental Act (Act No. 73 of1989) as it affects the planning professions.

These publications and more information about EPPICand its Regional Groups are available from the Secretary,EPPIC, P.O. Box 62041, Marshalltown 2107.

The Council of the CMMI agreed that the 15thCongress would be hosted by South Africa in 1994 duringthe centenary year of the SAl MM. An ExecutiveCommittee, including representatives of the miningindustry and the Geological Society of South Africa, hasbeen convened to start organizing this Congress, whichwill be hosted jointly by mining-industry organizations. Itis intended that the whole of Southern Africa should beinvolved in this Congress.

6.2 World Mining CongressNational Representative Dr H. Wagner

The International Organising Committee of the WorldMining Congress held meetings in New Delhi, India, andin Madrid, Spain. Unfortunately, it was not possible forthe South African members of the InternationalOrganising Committee to attend those meetings. Thearrangements for the 15th World Mining Congress, whichis to be held in Madrid, Spain, from 25th to 29th May,1992, are well advanced. In parallel with this Congress,there will be an International Mining Exhibition.

One of the international projects of the World MiningCongress is the publication of updated mining andmineral statistics. South Africa continued to provide therelevant infonnation.

6.3 APCOM '91

National Representative Prof. D.G. Krige

The 22nd APCOM Symposium was held from 17thSeptember to 21st September, 1990 in the modem ICC

320 SEPTEMBER 1991

Conference Centre in West Berlin. The facilities, whichwere excellent, included the simultaneous translation ofall proceedings into English, Gennan, and Russian. Thetwo main sponsors, the Technical and the FreeUniversities of Berlin, as well as the Stenkohl Research,the German Research Society, the Political Senate ofBerlin, and the German Academic Exchange Service, areto be congratulated on their organization and/orcontributions, financial or otherwise.

As has become customary at APCOM meetings, thesocial side and the programme for the forty-odd affiliateswere all of a high standard, as were the workshops andtours to mining, metallurgical, and other venues.

There were 389 registered participants from 35countries, of which the two with the largest number ofdelegates were Gennany (163) and South Africa (31). Themajor regions of Western and Eastern Europe, North andSouth America, Africa, the Middle and Far East, and Aus-tralasia were all represented. A feature of this symposiumwas the enthusiastic participation of Eastern Europe fromwhich there were 80 registrations, i.e. over 20 per cent ofthe total number.

A total of 425 abstracts was received, which had to bereduced to the final 169 papers published. The topicscovered were the usual, particular emphasis being laid onmining and also on computer-aided design (CAD) andexpert systems. Mineral processing and exploration couldhave received more attention.

Of particular importance to South Africa and theSAIMM was the election of Professor Danie Krige as thenew Chainnan of the International APCOM Council; he isthe fIrst non-USA member to occupy this position.

The next APCOM is being organized by the Universityof Arizona, and will be held in Tucson from 7th to 11thApril, 1992.

6.4 INF ACON '92NatiOl1ll1Representative Dr RE. Robinson

The sixth International Ferro Alloys Conference, whichis to take place from 9th to 12th March 1992, is beingjointly organized by the SAIMM, Mintek, and the FerroAlloys Producers' Association.

Arrangements by the Organizing Committee, under thechainnanship of Dr Robinson, are proceeding well and theCommittee is about to issue the final circular for theregistration of delegates. The Conference is to be held inCape Town, and the focal point will be the conferencecentre at the Cape Sun Hotel. The response to the firstcircular was disappointing, and urgent attention was givento the distribution of a second circular with a widercirculation. Responses to this second circular are stillbeing received, and have exceeded all expectations. It isstill not unlikely that over 500 delegates will be present. Alarge contingent is expected from overseas.

This will make Infacon one of the most prestigiousconferences to be held in South Africa, but will also strainthe accommodation facilities in Cape Town to the limit. It


is hoped to run the International Conference on Chromiumand Stainless Steel, also being organized by the SAIMM,concurrently.

The Institute will have the responsibility of publishingthe proceedings of the conference.

6.S International Chromium Steeland Alloys Congress (INCSAC)

National Representative 1.P. Hoffman

The above-mentioned Congress will be held in CapeTown from 8th to 12th March, 1992, in conjunction with,and parallel to, Infacon '92.

The Congress is being organized by the SAIMM, andwill provide a forum for engineers, technologists,scientists, fabricators, and managers who are concernedwith the production and application of chromium steelsand alloys.

INCSAC '92 will focus on new developments inprocess metallurgy, physical metallurgy, and theproduction and application of chromium-contained steelsand alloys in corrosive, abrasive, and elevated-temperature applications.

Some 50 papers, including those of invited, specialist,and keynote speakers, each an expert in his field, will beprd'ented. Some of these speakers will be from overseas.Delegates will also be given an opportunity to attend ajoint session with Infacon delegates on chromium andchromium alloys. .

Delegates from 23 countries are expected to attend theCongress. Early-bird registration forms are expected backby 30th November, 1991.

7. MANAGEMENT AND ADMINISTRATION

Portfolio Holder: H.G. Mosenthal

Our new office accommodation in Cape Towers isproving most satisfactory. All meetings apart from theCouncil meeting are held in the two committee rooms.The Council meetings are convened in the nearbyChamber of Mines Building.

Council members and the Secretariat contilJued to liaiseclosely. The following staff are employed in servicing theneeds of the Institute and its members: Mrs C. Mackintosh(Manager), Mrs P. Smith, Miss C. lansen, Mrs S.Moodley, Mrs K. Norman, and Mrs A. Panana. Ourcongratulations to Council member, Peter Smith, and MissPam Binstead who were married during the year.

With the withdrawal from typesetting of Mrs ClaireKeamey, it was decided that a desk-top publishing systemshould be purchased and additional staff employed toundertake the typesetting of our Journal and book-publications section internally.

It was with regret that Council accepted the resignationof our Treasurer, Dr H. Wagner. He will be replaced in the1991192year by Mc I.A. Cruise.

7.1 Forward Planning

The technical programme of the Institute continues tooperate on a four-year pIan to ensure that the activities ofthis Institute are co-ordinated with those of other societiesserving the mining industries in South Africa and abroad.

7.2 FinanceDr H. Wagner, Chairman

RD. Beck Dr H. Scott-RussellI.P. Hoffman DrO.K.H. SteffenH.G. Mosenthal

The Institute experienced a difficult financial year andrecorded a loss of R63 153. This loss can be attributed tothe following main causes.(i) The income from colloquia and schools was lower

than in previous years. This was because fewer eventswere organized and because of a drop in attendancefigures, which can be attributed to the economicdifficulties encountered by the industry.

(ii) The production costs of the Journal markedlyexceeded the budget, and account for most of the lossincurred by the Institute.

Steps have been taken to address these problem areas.The technical programme has been reviewed, and theemphasis is being placed on one-day events to keep coststo the industry Iow. The method of producing the Journalhas been reviewed, and should result in substantial cost-savings in the future.

As in previous years, the value of the stocks of booksand medals is shown, on the insistance of the auditors, inthe accounts at a nominal figure ofR5.

The book value of the Institute's investmentsdecreased by R133 569. The decrease was caused by twofactors. Firstly, in close consultation with the Institute'sinvestment advisers, the investment portfolio was re-structured to account for some major changes that havetaken place in the investment sector. Some low-yieldinginvestments were sold at a loss. Secondly, the Chamber ofMines of South Africa, which administers the Phoenixprogramme, withdrew RHO 000 from the Phoenix Fundto fmance a computerization programme. Accordingly, theInstitute was forced to sell some of its investments at aninappropriate time. Despite these facts, the market valueof the investments increased from RI 565 825 to RI 743225, reflecting a satisfactory performance of theinvestment portfolio. The total performance of theportfolio was 18,7 per cent compared to the performanceof the overall share index of 7,4 per cent, and the unit trustindex of 12,3 per cent.

As in previous years, most of the investment incomewas re-distributed to the various funds that are operatedby the Institute to maintain their value in real terms. Inline with this policy, an amount of R38 500 wastransferred to the various funds.

Despite the financial difficulties, it was decided tokeep the increases in membership subscriptions below the


level of inflation. This decision was taken in line with theInstitute's policy of financing its operation, as far aspossible, through activities in the field of technicalprogrammes and publications.

Thanks are due to Martin & Company, who continueto act as the Institute's financial advisers; to thesecretaries for their efforts in containing costs; and to theaccountant and auditor for excellent services renderedduring the year.
