Explain the extraction of zinc from its important ore

Concentration: The ore is crushed and then concentrated by froth-floatation Process. Roasting: The concentrated ore is then roasted in the presence of excess of air at Purification: Zinc is purified by electrolytic refining. In this process, impure zinc is anode and cathode is of pure thin sheet of zinc.

Zinc is extracted mostly from zinc sulfide ores. In this respect, the increasing demand of zinc and zinc compounds, and therefore new sources of zinc such as low grade oxide (2006) studied the zinc dissolution kinetics of smithsonite and hemimorphite in the lead flotation tailings by sulfuric acid. The maximum zinc extraction in optimum conditions was reported to be 73% of zinc content of ore.
