Environmentally friendly gold selection agent

Product Introduction:

Product Implementation Standard: Q/DSJ 01-2014

Scope of application: Applicable to the heap leaching, pool leaching, and carbon slurry (agitation leaching) process production of gold and silver oxide ores, primary ores, sulfide ores, cyanide tailings, and gold concentrates.

Product ingredients: sodium oxide, nitrogen, ammonium ions, calcium, iron, etc.

Product form: solid block or granular, easily soluble in water, and can be used after being dissolved in clean water.

Advantages:

1. Low toxicity and environmental protection: The product is non-flammable, non-explosive, has no oxidant hazard, no radioactive hazard, and is low in toxicity. It is a common chemical product, environmentally friendly and safe. The results of the toxicity test conducted by the Guangxi Center for Disease Control and Prevention (Guangxi Health Monitoring and Inspection Center) on the product showed that the acute oral toxicity LD50 of mice was 50.1mg/kgBW; the toxicity was lower than that of caustic soda (caustic soda LD50 was 40mg/kgBW).

2. Stable performance: reduce the interference of harmful substances such as arsenic As and sulfur S;

3. Strong applicability: suitable for heap leaching, pool leaching, and carbon slurry (agitation leaching) process production of gold and silver oxide ores, primary ores, sulfide ores, cyanide tailings, gold concentrates, etc., with large or small scales, more suitable for large-scale heap leaching production;

4. High leaching rate: effective leaching of gold ions, higher and faster than using sodium cyanide, and improved recovery rate;

5. Faster recovery: heap leaching production has a shorter cycle than using sodium cyanide (can be shortened by about 30%), and faster recovery;

6. More economical dosage: the efficacy is sustained and stable, and the dosage is more economical than similar products;

7. Lower cost: reduce the cost of procurement, transportation, storage, custody, use, safety and environmental protection facilities, etc.

8. Easy to use: the heap leaching production process is consistent with the method of using sodium cyanide, which is easy to use and promote;

9. Easy to transport: can be transported by road, rail, air and sea.
