The mineralogy of Tungsten

Important ores of Tungsten; The primary ore of tungsten is wolframite, which is a series between two mineral species, ferberite, the iron tungsten oxide, and hübnerite, the manganese tungsten oxide. Deposits of wolframite are generally from magmatic or hydrothermal origin. Concentration of workable ores is usually between 0.3% and 1.0% WO 3.

Tungsten Wikipedia

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite, and wolframite, lending the element its alternate name.
