Uses of Zinc: Used to coat other metals (galvanizing) to protect them from rusting. ![]() Primary mining areas are USA, Canada, Australia, Austria, Russia and Turkey. Annual world wide production is around 5,020,000 tons. Sources of Zinc: Found in the minerals zinc blende (sphalerite) (ZnS), calamine, franklinite, smithsonite (ZnCO 3), willemite, and zincite (ZnO).Name Origin: German: zink (German for tin).Note: this data represents naturally occuring levels of elements in the typical human, it DOES NOT represent recommended daily allowances.
