Zinc comes from natural mineral deposits of ore in the earth s crust. The deposits may be close to the surface, in which case they will be mined from an open pit. Alternatively, they may be some distance underground and cannot be mined directly from the surface.
The History of Zinc. Introduction. Long before the discovery of zinc as a metal, zinc ore was already being used to produce the copper-zinc alloy brass as well as zinc salts for medical purposes. Objects made of brass are known from Babylonia and Assyria from 3000 BC, and from Palestine dating from 1400 - 1000 BC.
