    zinc is extracted from either Zinc blende/sphalerite Ore or sometimes calamine/smithsonite Ore. zinc sulfide+oxygen gt;zinc oxide+sulfur oxide. Zinc is the fourth most common metal in use, trailing only iron, aluminium, and copper with an annual production of about 12 million tonnes.The world's largest zinc producer is Nyrstar, a merger of the Australian OZ Minerals and the Belgian Umicore.

    Zinc mining

    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.

    Zinc released to the environment follows a cycle (figure 1) in which zinc from mineral ore bodies is converted through extraction and refining processes from its mineral state (mostly sphalerite ore, zinc sulfide) into the metallic state. [5] Most of this metal will have a long service in stable metal applications and will be recovered and recycled at the end of life.
