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. Procedure of Zinc Extraction

The zinc tailings pass over a Table which gives the operator a constant, visual picture of the efficiency of the zinc flotation machine, and also recovers additional zinc values. Zinc concentrates are fed to a Table to remove any lead oxide values which may have floated with the zinc, and then are thickened in a Thickener.

Almost 29.57–38.46 million tons of zinc-bearing dust were produced in Chinese iron and steel enterprises annually. The recovery of Zn and other metals in zinc-bearing dust from ironmaking and steelmaking could improve economic efficiency. However, zinc-bearing dust was classified as hazardous waste, and the volatile metals (like Zn, Na, Pb, etc.) in zinc-bearing dust limited the …
