  • Leaching (metallurgy)

    Leaching is a process where ore is soluble and impurities are insoluble, widely used extractive . 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.
