The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.
