Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. Zinc has moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient. Its most important use, as a protective coating for iron known as galvanizing, derives from two of its outstanding characteristics: it is highly resistant to corrosion, and, in contact with iron, it provides sacrificial protection by corroding in place of the iron.
The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earth’s surface. Zinc is also used for Anti-corrosion coating for steel, brass and other metals, for Construction materials, for making of brass and for Cosmetics and pharmaceuticals.
