The process of removing the impurities from the ore is known as the concentration of ore. In this process, the ore is first crushed into small pieces and then is again crushed to form a powder. The powdered ore is then washed in a water current in which the lighter impurities are removed and the heavier ore is settled down. Calcination or roasting:
