Extraction of Zinc - Introduction, Mining, Procedure, and

Zinc Mining. 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 ...

Extraction of Zinc: Process, Methods, Diagarm, Examples

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n
