CNLITE Eco-friendly Gold Leaching Reagent
Usage: CNLITE is used in the same way as sodium cyanide in heap leaching, pool leaching and agitation leaching of gold ore. The reagent can be dissolved in solution with gold cyanide extraction. When used, the CNLITE gold leaching agent must be agitated with alkaline water at normal temperature and then dissolved in slurry for gold leaching.
Gold Metallurgy and Leaching Process
Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes ...
