Jul 28, 2012· The ore (crushed) is taken in a large tank containing oil and water and agitated with a current of compressed air. The ore is wetted by the oil and thus gets separated from the gangue in the form of froth. As the ore is lighter, it comes on the surface with the froth and impurities are left behind. d) Chemical Method or leaching:
