zinc production from ore to metal - bridgecursus-wijchen

Zinc production from ore to metal involves different stages. The process of zinc mining removes the ore from the earth. However, it is necessary to crush the ore and then separate the zinc from the other minerals. Zinc recovery from minerals can involve sintering and a pyrometallurgical process that requires a smelting furnace.

Extraction of Zinc - Introduction, Mining, Procedure, and FAQs

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. The best concentration method for zinc ore is froth flotation.
