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., …

The calcine has an acid reaction, and before it can be handled in contact with iron and steel, it must be neutralized. This is carried out in a preliming step in a 7- by 7-ft. turbo-agitator, which oxidizes the ferrous salts and precipitates the corrosive sulphates and chlorides present as hydrates.

If metallurgically possible, this is highly advisable, as 30% to 85% of the gold is usually dissolved here, thus greatly relieving the metallurgical load on the agitators. The dissolving conditions in the grinding circuit are ideal, as the fresh metallic faces, as exposed, are instantly brought in contact with the cyanide solution, which ...

Counter-current leaching. leaching efficiency can be enhanced by the application of Le Chatelier's principle. In summary, the lower the concentration of gold in solution, the greater the driving force for gold dissolution to occur, although in a mass transport controlled reaction it is debatable what role this plays in gold leaching.
