No other metal mimics gold better than tungsten. Not found in the earth in its pure state, it’s found only in a few, rare minerals. The best source of tungsten is the mineral Scheelite that is composed of calcium and tungsten.This ore mineral is named after Karl (sometimes shown as Carl) Wilhelm Scheele, a Swedish chemist who found, in 1781, that the mineral contained an acid he named Tungsten. When heated with carbon, it produced metallic tungsten.Tungsten is also found in Wolframite, and with manganese and iron. Tungsten ore is mainly found in China. Other countries that produce it are the U.S., Brazil, Peru, Bolivia, Argentina, Spain, and Southern Rhodesia.In the U.S., the main production states are California, Nevada, North Carolina, Idaho, Colorado, and Arizona.
