It is the process of extraction of zinc from its ores, and the preparation of zinc metal for use in various products. The most commonly available ore in the extraction of Zinc is Zinc Blende also known as Zinc Sulphide (ZnS) and other ores include Calamine, Zincite, etc. Zinc Blende does not contain a very high percentage of zinc so it needs to be concentrated.
