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
