Principle: This method is used when the ore is a sulphide or a carbonate. Example: Concentration of Zinc Ore using Roasting: Zinc ore is heated in the presence of excess oxygen. The sulphide ore is converted to oxide, and volatile impurities are expelled. Heating: The ore is subjected to high temperatures in the presence of air.
