    The froth is skimmed off and the resulting zinc sulphide concentrate is dried. This process upgrades the ore, which may contain only 6% zinc, to a concentrate assaying more than 50% zinc. Up to 90% of the zinc in the ore can be recovered. Electrolysis and smelting are the two processes used to produce zinc metal

    Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient

    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 …
