Gold And Nickel Ore Leach Processing

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
