Alias: gold concentration agent, gold beneficiation agent, metal concentration agent
Product nature
Product appearance: Grey white solid particles or powder (a small amount of black insoluble matter does not affect leaching);
Physical and chemical properties: Polymeric cyanamide type gold and silver leaching agents. It is easily soluble in water and insoluble in organic solvents. The aqueous solution is alkaline and decomposes when exposed to acid, releasing irritating gases. Contact with acid should be avoided. It has hygroscopicity and should avoid prolonged exposure to humid air.
Applicable scope
Used for gold leaching processes such as full mud leaching - carbon slurry adsorption, full mud leaching - resin adsorption, full mud leaching - zinc powder replacement, heap leaching, etc.
Product Features
1. After use, the total cyanide content of tailings is less than 5mg/L, which meets the environmental protection requirements of the "Technical Specification for Cyanide Residue Pollution Control in the Gold Industry" for tailings;
2. The leaching rate is stable, consistent with or slightly higher than sodium cyanide;
3. The drug consumption is 25% -30% lower than other similar drugs, and the leaching rate is more than 1% higher than similar drugs;
4. The product has low impurity content, no pipeline crystallization blockage, and the adsorption and desorption effect of activated carbon is much higher than that of other reagents;
5. Non hazardous goods, convenient for transportation and storage.
Storage and transportation methods
The product has hygroscopicity and should be stored in a cool, dry, sealed package. Pay attention to moisture-proof and moisture-proof measures. Prevent oral inhalation by humans and animals. It is strictly prohibited to coexist with acidic chemicals, edible chemicals, and oxidants. It is strictly prohibited to mix with acids, oxidants, food and food additives for transportation. During transportation, it is necessary to prevent exposure to sunlight, rain, and high temperatures.
