Overview
Why need use new gold dressing agent:
The cyanide used in the cyanide process has three major shortcomings:
1. It is highly toxic, seriously endangering human and animal life, polluting the ecological environment, and has no development prospects at all;
2. The deterioration of technical and economic indicators for complex ores is highly inconsistent with the characteristics of China's gold ore and the changing trends of world gold resources;
3. The slow leaching speed naturally prolongs the operation cycle, resulting in low equipment utilization efficiency; Therefore, conducting research on alternative drugs for cyanide (cyanide free gold leaching agents) has significant economic and environmental ecological significance. It is also a difficult problem that our country must overcome in moving towards a beautiful China.

Working principle
Gold dressing agent Advantages
1. High recovery rate
Strong complexation ability, effective leaching of gold and silver from ores, and high leaching rate.
2. Short leaching time
The leaching cycle is shorter than using sodium cyanide (which can shorten the leaching time by 15-30%) and the recovery is faster.
3. Strong anti-interference ability
Add effective stabilizers to reduce the interference of harmful substances such as arsenic As, sulfur S, and carbon C.
4. Easy to use
The product is easily soluble in water, and the usage method is basically the same as that of sodium cyanide, making it easy to prepare and use.
5. Widely applicable
Adapted to the production of heap leaching, pool leaching, and carbon slurry processes in gold mines, the scale can be large or small.
6. Lower usage cost
Due to product safety and environmental protection, it can effectively reduce the cost of approval, storage and transportation, and safety and environmental protection facilities caused by the use of sodium cyanide.Gold dressing agent Application:
The production process of gold ore dressing agent in heap leaching, pool leaching, and carbon slurry (stirring leaching) of gold and silver oxide ore, primary ore, sulfide ore, cyanide tailings, and gold concentrate is the same as the process of using cyanide sodium, and precious and lean liquids can be reused in production
