Zinc smelting - Wikipedia

There are also several pyrometallurgical processes that reduce zinc oxide using carbon, then distil the metallic zinc from the resulting mix in an atmosphere of carbon monoxide. The major downfall of any of the pyrometallurgical process is that it is only 98% pure; a standard composition is 1.3% lead, 0.2% cadmium, 0.03% iron, and 98.5% zinc. This may be pure enough for galvanization, but not enough for die casting alloys, which requires special high-grade zinc (99.995% pure). In order to reach this purity the zinc must be refined.

Zinc and Lead - Glencore

Zinc is mainly used to galvanise steel or iron – that is, to apply a zinc coating to stop it rusting. Galvanised steel is used in buildings, cars, white goods and electronics. The strength and flexibility of zinc alloys mean they are widely used to create die casts for industrial uses – for example, in the production of car or machine parts.

Zinc processing | Britannica

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.
