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, …
