Metallurgy of Zinc. The principal ore of zinc used for its extraction is Zinc blend (ZnS) ( 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 1200K 1200 K to obtain zinc oxide (ZnO) ( Z n O). It is then reduced to Zn Z n by coke ...
