Extraction of Zinc Application Of Zinc Refining Process

2015-12-9  The carbon from coke acts as the reducing agent in this reaction. The reaction of the final step of extraction of zinc is \(2 ZnO + C \rightarrow 2 Zn + CO_{2}\) Since, the boiling point of Zinc is way back at 1180 K, the zinc formed immediately vaporizes and distills over leaving behind non-volatile impurities such as Cadmium, Lead and Iron.

Extraction of Zinc - Introduction, Mining, Procedure,

2021-5-3  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
