Zinc production & environmental impact - GreenSpec

Zinc is commonly found in mineral deposits along with other base metals, such as copper and lead. Zinc deposits are broadly classified on the basis of how they are formed. Zinc is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).

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.
