Cyanide is widely used in gold leaching industry in the past years, it is cheap and suitable for leaching process, but high-poisonous and bad to environment. CNLITE gold leaching reagent can replace cyanide in gold leaching plant without changing the original process and equipment, and it’s eco-friendly and low-poisonous. It’s a good choice for gold leaching plants.

Choosing the flotation reagent is crucial for flotation process. In the flotation process, in addition to using water as a medium, it is necessary to add additional reagents, which can separate useful minerals from gangue minerals effectively, or to separate various useful minerals. And these reagents are more beneficial to flotation among minerals ...

The principle of gold extraction by using mercury (amalgamation method) is mainly that after the mercury is added to the slurry, the surface of the gold particles is wetted by mercury, and then the mercury diffuses into the interior of the gold particles, causing a chemical reaction. Au+2Hg=AuHg2. Finally, the solid of Au3 Hg will form. When the obtained solid matter is heated, the mercury will volatilize into an elemental form, and the gold will exist in the form of sponge gold.
