History, Deposits, and Production of Zinc

Mar 30, 2020  Rock with these high zinc contents is known as ore. The ore contains zinc mostly in the form of sphalerite, i.e., as so-called zinc blende (ZnS), and along with zinc scrap, is the most important raw material for zinc production. Zinc ore is often mined in open pits.

Zinc mining - Wikipedia

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 ...

Uses of Zinc Supply, Demand, Production, Resources

Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.

1 Zinc ores are dug from underground mines using conventional blasting, drilling, and hauling techniques. The ores occur as zinc sulfide (also called sphalerite), zinc carbonate (smithsonite), zinc silicate (calimine), and in compounds of manganese and iron (franklinite). Zinc ore is sometimes mined in conjunction with silver or lead ores.
