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 minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such as ...

The chief Ore of zinc is zinc blende. The extraction of zinc from zinc blende involves the following steps. Concentration: The ore is crushed and then concentrated by froth-floatation Process. Roasting: The concentrated ore is then roasted in the presence of excess of air at about 1 2 0 0 k: 2 Z n S + 3 O 2 → Δ 2 Z n O + 2 S O 2
Zinc's History. Zinc was formally discovered as an element by Andreas Sigismund Marggraf, a German chemist who isolated it in 1746.. However, long before this discovery, civilizations were using zinc. According to the journal Ancient Asia, miners were smelting zinc in India by the ninth century BC.. During the Roman Empire, soldiers forged brass weapons from copper and zinc, and …
Zinc blende, also known as sphalerite, is the chief ore of Zinc,it consists largely of Zinc Sulfide.. Extraction of Zinc from Zinc Blende. The extraction of zinc from zinc blende consists mainly of these two following processes. Firstly, Zinc blende is crushed and heated in air.This allows the zinc sulfide in the ore to react with oxygen in the air and produce zinc oxide.
