Zinc (from German: Zink), also known as spelter, is a metallic chemical element; it has the symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table.
Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2. The most exploited zinc ore is sphalerite, a zinc sulfide. Zinc production includes froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
