Tungsten

Tungsten has thus far not been found in nature in its pure form. Instead, tungsten is found mainly in the minerals wolframite and scheelite. Wolframite is iron–manganese tungstate (Fe,Mn)WO4, a solid solution of the two minerals ferberite (FeWO4) and hübnerite (MnWO4), while scheelite is calcium tungstate (CaWO4). Other tungsten minerals range in their level of abundance from moThe chief source of Tungsten are wolframite [(Fe,Mn,)WO4], and scheelite (CaWO4). The State has about 23.92 million tonnes resources of tungsten ore which is Metallic Minerals Rajasthan

tungsten in India that produced meagre quantities of concentrate. These mines, owing to economic non-viability, had to be closed down. USES Tungsten is mainly used in the form of ferro-tungsten in making of special and alloy steels. Ferro-tungsten typically contains between 25% and 75% tungsten. The other principal use ofTungsten is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.Tungsten Wikiwand
