extracting zinc from its ore

Zinc processing Britannica

Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient.

Extraction of Zinc Application Of Zinc Refining Process

Dec 09, 2015The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas. Due to its very low boiling point, at such temperatures, zinc will

Zinc processing Ores Britannica

The most common underground method of ore extraction is cut-and-fill stoping, in which tunnels are dug to moderate depths, branching away from the mine portals. The small fraction of zinc sulfide minerals present in the ore makes beneficiation necessary in order to produce a concentrate suitable for treatment.
