steps involved in the extraction of zinc

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.

The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit.
