Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through zinc mine is a mine that produces zinc metal. Some mines produce primarily zinc, but some mines produce zinc as a sideproduct of some metal that has a higher concentration in the ore.
The name "zinc" only came into general use in the 17th century following rediscovery of the material. As zinc only ever occurs in Nature in the form of compounds, it was initially produced from carbonate of zinc, a zinc salt. Zinc was found to be especially suitable for alloys with other metals and was therefore first of all employed to make coins.
