Zinc Sulfide - an overview | ScienceDirect Topics
Zinc. The most common ore is zinc blende (ZnS), which is found in association with lead, iron, and other sulfides. Before smelting, zinc sulfide is usually concentrated by a float and sink method. The zinc sulfide is then roasted to form zinc oxide, followed by reduction with carbon and/or carbon monoxide. Zinc metal is distilled off.

The nonsulphide zinc ore (smithsonite) has been formed (1) in paragenetic association with the sulphide ore, and (2) by supergene in-situ oxidation of the sphalerite ore. The fixation of the mobilised zinc as smithsonite was promoted by the buffering action of (CO 3 ) 2− that was delivered from dissolution of the calcite in the hanging wall.
