Environmentally Friendly Gold Extractant Used in Mining Metallurgy

Applicable beneficiation process: dump leaching, pool leaching and carbon pulp (agitation leach) etc.

2. Jinchan Product Form: solid lump or graininess
3. Jinchan Dissolution Method: it can be used after being fully dissolved by water under normal temperature (in general, the dissolution can be accelerated in flowing water or through full stirring; dosing pool can be built near to the barren solution pool in heap leaching process in order to let backwater which has passed carbon directly wash Golden Cicada and dissolve it into barren solution pool);

4.Alkalinity Adjustment: in general, adjustment is carried out with lime or causti c soda with stable pH value between 11-12; when the pH value of backwater 
decreases, alkalinity shall be timely adjusted; when the pH value is too high (more than 12) for a very long time, alkali dirty will be generated and affect the 
activated carbon adsorption or the liquid passivation will occur and affect the leaching effect);
5.Dosage Calculation
The dosage of Golden Cicada can refer to the dosage of sodium c yanide. It is recommended to carry out beneficiation test and refer to its optimum 
conditions; (1-2 g/t gold oxidized ore is common and the Golden Cicada concentration is generally maintained between 0.3-0.8 ‰. Make proper 
adjustment in accordance with different ore grades and harmful component);
Calculation method of dosage: Added dosage of Golden Cicada=(optimum concentration value-measured concentration value)×water volume in 
dosing pool; assuming that the optimum concentration value of Golden Cicada is 1.5 ‰ (calculated as per water volume), the backwater Golden Cicada 
concentration is 0.6 ‰ and barren solution pool has water of 500 square meters, then the added dosage of Golden Cicada is (1.5-0.6)×500=450 kilograms.

6.Product Use Flow: (in accordance with dump leaching and carbon leaching process with the use of sodium c yanide)
Process of heap leaching and pool leaching: raw ore crushing, entering pump/pool, leaching, activated carbon adsorption  replacement),  resolution electrodeposition and smelting;
Carbon pulp process (agitation leach): raw ore crushing, ore grinding, carbon leaching, electrolysis and smelting;
