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 gold, silver or copper. Mined ore is processed, usually on site, to produce one or more metal-rich conce

Zinc processing - Ores | Britannica

Zinc ores are recovered by many mining techniques, ranging from open-pit mining (mainly in the case of oxidized ore bodies, which are located closer to Earth’s surface) to the normal underground methods (used for the more deeply located sulfide ores). The most common underground method of ore extraction is cut-and-fill stoping, in which tunnels are dug to moderate depths, branching away from the mine portals.

LEAD ZINC EXTRACTION PROCESSES - EPrints

The most important lead ore is galena (lead sulfide). Other important ores such as cerrusite (lead carbonate) and anglesite (lead sulfate) may be regarded as weathered products of galena and they are usually found nearer to the surface. Lead and zinc ores often occur together and for most extraction methods they have to be separated.

Gold recovery from copper-zinc ores is usually higher than that obtained from either a lead-zinc or copper lead-zinc ore.This is attributed to two main factors: when selecting a reagent scheme for treatment of Cu-Zn ores, there are more choices than for the other ore types, which can lead to the selection of a reagent scheme more favourable for gold flotation.
