China manufactures Jinchan metal ore dressing agent for sale gold leaching agent

Product Description

Jinchan environmentally friendly gold dressing agent is a new high-tech product independently developed by Guangxi Senhe High-tech Co., Ltd. to replace sodium cyanide for gold dressing. At present, Jinchan dressing agent is the only product in the world that has obtained the "environmentally friendly gold extraction" patent. This product does not require changes to the original process and can directly replace sodium cyanide for gold production.

Product Features

1. Low toxicity and environmental protection
The product is non-combustible, non-explosive, has no oxidant hazard, no radioactive hazard, and is low in toxicity. It is a general chemical product that is environmentally friendly and safe.
2. High leaching efficiency
It has strong complexing ability and can effectively leach gold and silver from ores with a high leaching rate.
3. Strong anti-interference ability
The product has stable performance and strong anti-interference ability. A small amount of harmful substances such as arsenic As and sulfur S in the ore will not affect the leaching effect.
4. Easy to use
This product is easily soluble in water and its usage is the same as that of sodium cyanide. It is easy to prepare and use.
5. Strong adaptability
It is suitable for heap leaching, pool leaching, stirring leaching and other production processes of oxidized gold ore.
6. Low cost of use
Because of the safety and environmental protection of this product, it can effectively reduce the high costs in procurement, transportation, storage, custody, use, safety and environmental protection facilities caused by the use of sodium cyanide.

Product Description

1. Applicable ore types
Gold and ores, primary ores, tailings, smelting slag, fine powder, flue ash, etc.;
2. Applicable process types
Heap leaching, pool leaching, tank leaching, stirring leaching + activated carbon adsorption (resin exchange or zinc powder, zinc wire replacement);
3. Product ingredients:
Components such as alkali, chloride, ammonium, oxygen, sulfur, calcium, and iron;
4. Product form
Gray powder, easily soluble in water;
5. Product dosage:
200-1500 g/ton of ore;
6. Product Use
The usage of environmentally friendly gold agent is the same as that of sodium cyanide. In the production process, precious liquid and inferior liquid can be reused, and activated carbon (zinc powder, zinc wire replacement or exchange resin) is used for precious liquid gold adsorption. The gold leaching effect is best when the ambient temperature is above 10℃, and sodium cyanide can be added at the same time.
(1) Heap leaching (tank leaching) process: prepare a 0.03-0.1% solution with clean water for spraying (or tank leaching);
(2) Stirring leaching process: 10%-15% solution can be added, or directly added to the stirring tank in solid form. The concentration of reagent in the leaching slurry is generally in the range of 0.03-0.1%.
