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.

Zinc processing - Ores Britannica

Zinc processing - Zinc processing - Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine

Zinc smelting - Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphale

Uses of Zinc Supply, Demand, Production, Resources

Sphalerite: The Primary Ore. Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.
