Zinc Sulfide - an overview | ScienceDirect Topics
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.

· Zinc sulfide (ZnS), a naturally occurring salt, is the main source of zinc. It has two common crystalline forms (polymorphs): Sphalerite ("zinc blende"), with a cubic crystal structure, is the form that predominates in nature. Wurtzite, with hexagonal crystals, is scarcer, but it can be made by heating sphalerite to ≈1020 ºC. 1.
