Zinc Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).Zinc processing BritannicaThe zinc content of mined ore is usually between 3 and 10 percent. Almost all ores contain the lead sulfide mineral galena and small quantities of cadmium sulfide. Chalcopyrite, and copper iron sulfide, is often present. The
