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.
