Extraction of Zinc | Application Of Zinc Refining Process

The reaction of the final step of extraction of zinc is (2 ZnO + C -> 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. This gas containing zinc vapours is collected and cooled to yield solid zinc.
