gold gold gold leaching process in russia

Leaching, oftengold, is theprocessof extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, ofgold, it is theprocessof 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 ...
