Concentration of Ore Definition, Types and Properties

There are numerous methods of concentration and the methods are chosen based on the properties of the ore. Hydraulic Washing: This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore.

Conversion of the enriched ore into the oxide of metal

Hence, the concentrated ore is converted into the oxide of metal which is then reduced to metal. This conversion to oxide is done by the process of calcination or roasting. In this process the ore is heated very strongly in the absence of air, keeping the temperature below its melting point so that volatile impurities are driven off.

Conversion of the enriched ore into the oxide of metal

HgS + O 2 → Hg + SO 2. (iv) Iron pyrite (FeS 2) is converted into ferric oxide (Fe 2 O 3) by roasting. 4FeS 2 + 11O 2 → 2Fe 2 O 3 + 8SO 2. Thus, both calcination and roasting produce oxide of the metal. However, there are a few points of difference between the two processes. Chloride ores remains unchanged by calcination or roasting.
