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.

How is zinc extracted from zinc blende? - Sarthaks ...

Zinc blende is ZnS. For the extraction of zinc from zinc blende, the ore is first concentrated by the method of froth floatation. The concentrated ore is then roasted by heating the ore in the presence of oxygen to give ZnO releasing SO 2.The ZnS is further reduced using coke at temperature of 673 k giving zinc metal.
