Extraction of Zinc Application Of Zinc Refining Process

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.
