Leaching is a chemical process of concentration of ore. Here the ore dissolves in a chemical solution. The minerals will react and dissolve leaving behind the impurities only which filter out. And then the metal will be obtained from the chemical solution. Let us now take a look at an example of how we obtain Aluminium by leaching. Bayer Process
