Product Description

CNFREE Environmental-friendly Gold Dressing Agent, used in gold production directly as the substitute for sodium cyanide without changing original process and equipment enjoys advantages such as low toxicity, environmental protection, high recovery, good stability, convenient operation, quick recycle, low dosage, low cost and convenient storage and transportation.

Product Description

CNFREE Environmental-friendly Gold Dressing Agent, components are calcium, sodium oxide, ammonium and other 10 kinds of components with complex machines after testing is environmental toxicity of gold flotation reagent, can completely replace sodium cyanide in gold extraction effect, with the national attention to the environmental protection, the government of sodium cyanide banned the use of, the current market development space is very large. Products suitable for gold and silver ore heap leaching, pool leaching, coal production process. Product use effect is good: product stability, good performance, relative to the cyanide leaching rate is higher, the leaching time is faster, the efficacy of the stability, the use of safe and environmentally friendly.

Product Instruction

Applicable ore types: golden and silver oxidized ore, primary ore, high-sulfur and high-arsenic gold ore, cyanidation slag, gold concentrate, pyrite cinder and anode mud etc;

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

2. Product Form: solid lump or graininess
3.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 product and dissolve it into barren solution pool);
4.Alkalinity Adjustment: in general, adjustment is carried out with lime or caustic 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);

The dosage of product can refer to the dosage of sodium cyanide. 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 product 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 product =(optimum concentration value-measured concentration value)×water volume in dosing pool; assuming that the optimum concentration value of product is 1.5 ‰ (calculated as per water volume), the backwater product concentration is 0.6 ‰ and barren solution pool has water of 500 square meters, then the added dosage of product is (1.5-0.6)×500=450 kilograms.

Product Advantages

1. Low toxicity and environmental protection: the product is non flammable, no explosion, no oxidant risk, no radioactive hazard. Is a common chemical products, environmental protection and safety.
2. Stable performance: reduce the arsenic As, sulfur S and other harmful substances;
3. Applicability is strong: applicable to the oxidation of gold and silver ore heap leaching, leaching pool, carbon in pulp production process, and the scale can be big or small, more suitable for large scale heap leaching production
4. The leaching rate is high: the effective leaching of gold ions, higher than the use of sodium cyanide higher and faster, improve the recovery rate;
5. Recycling faster: heap leaching production than the use of sodium cyanide cycles shorter (can be shortened to about 30%), recovery faster;
6. The dosage of the province: the efficacy of continuous stability, more than similar products;
7. Lower cost: reduce procurement, transportation, warehousing, storage, use, safety and environmental protection facilities, etc.;
8. Easy to use: heap leaching process and the use of sodium cyanide method is consistent, easy to use and promotion;
9. Easy to transport: can be used in highway, railway, aviation, maritime transport.
