Zinc Ores - ChestofBooks.com
Extraction Of The Metal. The principle which governs the extraction of zinc from its ores is that the metal is readily volatilized and easily recon-densed. The first step necessary with ores other than oxides is a calcination to remove the sulphur or other base and convert the zinc to an oxide; the next step is to smelt the oxide with carbon, by which the carbon and oxygen are combined to form

Review of the hydrometallurgical processing of non-sulfide
In order to find a better way to leach non-sulfide zinc ores, especially silicate ores, many researchers have examined different methods, such as mechanical activation, pressure leaching, and microwave irradiation to increase zinc recovery during the leaching of non-sulfide zinc ores. 6.2.1. Mechanical activation

Extraction of Zinc | Application Of Zinc Refining Process
The reaction of the final step of extraction of zinc is 92;(2 ZnO + C -gt; 2 Zn + CO^{2}92;) 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.
