Explain the extraction of zinc from its chief ore.

Zinc: The important ores of Zinc are Zinc blende, Z n S Calamine, Z n C O 3 Zincite, Z n O The extraction of zinc blende involves the following steps (i) Concentration: The ore is crushed and then concentrated by froth-floatation process. (ii) Roasting: The concentrated ore is then roasted in the presence of excess of air at about 1200K.

How is Zinc Extracted from Its Carbonate Or (Calamine

2021-1-15  1. Concentrated carbonate of zinc is converted to its oxide by calcination. In this process, zinc carbonate ore is strongly heated in the absence of air to produce zinc oxide and carbon dioxide gas. 2. Zinc oxide is then reduced by coke (carbon). When zinc oxide is heated with coke, carbon acts as a reducing agent and reduces zinc oxide to zinc.
