Sources. Zinc is mined from several different minerals, including sphalerite (zinc sulfide), smithsonite (zinc carbonate), hemimorphite (zinc silicate) and zincite (zinc oxide). Other zinc-bearing minerals include willemite and hydrozincite. Zinc ore is mined in Canada, Australia, the USA, China, Peru.
Calamine is a historic name for an ore of zinc. The name calamine was derived from lapis calaminaris, a Latin corruption of Greek cadmia (καδμία), the old name for zinc ores in general. The name of the Belgian town of Kelmis, La Calamine in French, which was home to a zinc mine, comes from that.

Sphalerite, which is a form of zinc sulfide, is the most heavily mined zinc-containing ore because its concentrate contains 60–62% zinc. Other source minerals for zinc include smithsonite (zinc carbonate), hemimorphite (zinc silicate), wurtzite (another zinc sulfide), and sometimes hydrozincite (basic zinc carbonate).
Zinc ore occurs in two types of deposit: as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore is most commonly found as zinc carbonate (ZnCO 3), known as calamine or smithsonite.
When zinc deficiency does occur, it is usually due to inadequate zinc intake or absorption, increased losses of zinc from the body, or increased requirements for zinc [26,27,34]. People at risk of zinc deficiency or inadequacy need …

In Victoria zinc occurs in most gold–sulphide and lead–silver deposits. However the only major deposits of zinc identified to date have been in the far-east of the state near Wilga near Limestone Creek. This deposit was mined for its copper and silver from 1993 to 1996, but produced 16,894 tonnes of zinc from 956,980 tonnes of ore.
