cyanide processing plant for zinc

  • 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.
