CASE STUDY 4

Goldix 570 extracting reagent used in a Chinese Yunnan Gold Mine

In September of 2010, Florrea Goldix 570 is used in the heap leaching production of oxidized gold ore of

one Chinese gold sites. It turns out to be reliable in performance and effective in use to replace sodium

cyanide completely.

Ore characteristics: Fine water permeability of oxidize mines, little impurities and easy leaching.

Ore volume of storage yard: 4000 mts

Average grade of gold ore: 0.5g/t

Period for Spraying: 40 days

Grade of tailings: 0.060.08g/t, Leaching rate: 85%

CASE STUDY 5

Goldix 570 extracting reagent used in a Chinese Gold Tailings

In October 2010, Goldix 570 is used for the gold tailings at four storage yards of the ore site.

Ore characteristics: large sediment percentage, poor permeability. After raking over the ore, Florrea Goldix 570 was used for leaching.

It is proved that Goldix 570 is compatible with sodium cyanide.

Ore storage of each story yard: 800012000 mts

Average tailing gold assay: around 0.23g/t

Period for spraying: 40 days

Tailing gold assay: 0.070.1g/t . Leaching rate: 70 %.

CASE STUDY 6

Goldix 570 extracting reagent used in a Chinese Gold mine

As sodium cyanide is prohibited in this region in China, environmental protection has become a bottleneck for gold ore

manufacturing in the area. Oxidized ore of this gold deposit is faintly acid, and has high content of silt and carbon. Furthermore it

contains harmful elements such as like sulphur and arsenic, This ore is regarded as difficulty ore to process.

1 In May 2011,Plant trial using Florrea Goldix 570 environmental friendly gold extracting reagent is done in the Gold Mine.

The test ended in July 2011, lasting 50 days.

Gold Ore volume treated : 3000 mt.

Average gold assay at the storage yard: 0.48 g/t.

Spraying period: 40 days.

Tailing gold assay : 0.050.08g/t.

Leaching rate : 80 %

2 In Feb 2012, this gold ore is put into production

Annual ore processing capacity: one million cubic meters

Gold leaching extracting reagent : Florrea Goldix 570

Volume of each batch of ore simultaneously in heap leaching amounts to: 250,0003000,000 cubic meters.

CASE STUDY 7


China YNMJ Gold Mine (large Gold Mine)

Annual gold ore processing volume : 1.5 million cubic meters.
