Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc is necessary to modern living, and, in tonnage produced, stands fourth among all metals in world production - being exceeded only by iron, aluminum, and copper. Zinc uses range from metal products to rubber and medicines.
Description Zinc is used in a wide variety of applications, so it is necessary to break down the uses of zinc ores and concentrates into general categories: Zinc is used in the production of galvanized steel, zinc sheet, and zinc flake. Zinc is used in the production of batteries, as zinc oxide is a key component in the cathode.
