Gold mine derivative products

Cyanide-free environment-friendly gold extractor is an innovative product developed by technicians for many years, which can completely replace highly toxic sodium cyanide. With completely independent intellectual property rights, it is suitable for tank leaching or heap leaching of gold and silver oxide ores. It is superior to sodium cyanide in the production and application of gold and silver mines, and has the advantages of environmental protection, non-toxicity, strong gold dissolving ability, good stability, quick recovery, less dosage, low cost, convenient storage and transportation, etc. And truly realize "green mines, environmental protection and gold extraction".

The cyanide-free environment-friendly gold extracting agent has the following characteristics:

① Safe and non-toxic, which can reduce the environmental protection cost of gold concentrator to the maximum extent.

② The leaching speed is fast. Generally, the leaching rate can reach more than 90% within 6 ~ 8 hours. Therefore, the production efficiency is high and the leaching operation is convenient, which can be completed at room temperature and in the medium with pH value of 3 ~ 1 1.

③ The leaching rate is high. Leaching tests carried out in many mines illustrate this point.

④ The sensitivity to associated metals is low, and the leaching process does not depend on oxygen in the atmosphere. Therefore, the leaching production is less affected by the properties of ore, and the leaching solution can be recycled.

⑤ Good chemical stability and low dosage.

⑥ The raw materials for drug production are sufficient and the price is stable.

⑦ The new series of gold leaching reagents is complete, and the best reagent can be selected according to the characteristics of ore.

Matters needing attention

1. Because different ores have different compositions and pH values, it is necessary to prepare reagents according to the optimal reagent concentration obtained from the actual ore leaching test, and put gold extraction agents in proportion. The drug concentration can be detected by the method provided by our company.

2. When this reagent is used to extract gold, zinc powder replacement method is not suitable for the subsequent process, and carbon adsorption or ion exchange resin method can be used.

3. The product is non-flammable, non-explosive, non-oxidant, non-radioactive and non-dangerous, and can be transported by road, railway, sea and air;

4, the product is easy to absorb moisture, should be moisture-proof, moisture-proof, waterproof, sealed, sealed and packaged in a cool and dry place;

5. Products should be stored in isolation, and it is forbidden to store them in containers mixed with acidic chemicals and edible articles;

6. Prevent people and animals from eating by mistake;

7. Establish and improve the system of safe production and use of this product according to relevant national regulations.
