Extraction of Zinc Application Of Zinc Refining
网页The reaction of the final step of extraction of zinc is. 2 Z n O + C → 2 Z n + C O 2. Since the boiling point of zinc is way back at 1180 K, the zinc formed immediately vaporises and distils 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.
