Extraction of Zinc Introduction Mining Procedure and FAQs

Extraction of Zinc Introduction Mining Procedure and FAQs

The reaction involved in the final step of extraction of zinc is: ZnO + C → Zn + CO. Purification: The last step involves the purification of Zinc, Zinc is purified by electrolytic refining. In this process, impure zinc is anode and cathode is of a pure thin sheet of zinc and the electrolyte used is ZnSO 4 solution containing a small amount of H 2 SO 4. On passing the electric current pure zinc gets deposited on the cathode side.
