Leaching (metallurgy) Wikipedia
Leaching is done in long pressure vessels which are cylindrical (horizontal or vertical) or of horizontal tube form known as autoclaves. A good example of the autoclave leach process can also be found in the metallurgy of zinc. It is best described by the following chemical reaction: 2 ZnS + O2 + 2 H2SO4 → 2 ZnSO4 + 2 H2O + 2 SThis reaction proceeds at temperatures above the boiling point of water, thus creating a vapour p
