Extraction of Zinc | Application Of Zinc Refining Process Zinc Mining. The 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. Get price
Fig. 1. Flow diagram of the copper solvent extraction process. In the extraction units, copper is extracted from the pregnant leach solution to the organic solution. In the stripping units, copper is stripped from the loaded organic solution to the electrolyte solution. The resulting rich electrolyte solution is led to the electrowinning process.
Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining.A zinc mine is a mine that produces zinc metal. Some mines produce primarily zinc, but some mines produce zinc as a side-product of some metal that has a higher concentration in the ore.
