Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning). Zinc is an essential trace element for humans, [8] [9] [10] animals, [11] plants [12] and for microorganisms [13] and is necessary for prenatal and postnatal development. [14]
In 2019, 552,400 tonnes of zinc, 71 percent of US mined zinc production, and 4.2 percent of world zinc production, came from Teck Resources' Red Dog mine, the world's most productive zinc mine, in northwest Alaska, near Kotzebue. [2] [3] [1] The mine opened in 1989. [4] The zinc is shipped as concentrate to foreign smelters.
[4] [11] Developing a zinc, lead and silver mine near the U.S. and Mexico border, Arizona Mining gained recognition for its discovery of the Taylor deposit, one of the world’s largest zinc deposits, which was discovered by Don Taylor. [12] In 2018, Arizona Mining was bought out for C$2.1 billion by Australian miner, South32. [13] [14]
