2017629&ensp·&enspTungsten is used in aerospace and automotive industries and radiation shielding [4]. • Chemical appliions: Tungsten (IV) sulphide is a high temperature lubricant and is a component of alysts for hydrodesulfurization [5]. Tungsten oxides are used in ceramic glazes and calcium/magnesium tungstates are used widely in fluorescent lighting.
Pure tungsten is ductile, and tungsten wires, even of a very small diameter, have a very high tensile strength. Tungsten is highly resistant to corrosion. It forms tungstic acid (H 2 WO 4), or wolframic acid from the hydrated oxide (WO 3) and its salts are called tungstates, or wolframates.

Many centuries ago midEuropean tin smelters observed that when a certain mineral was present in the tin ore, their yield of tin was much reduced. They called this mineral 'wolfs ' because, they said, it devoured the tin much like a wolf would devour a sheep! Thus over time the name 'wolframite' evolved for this tungstencontaining ore.

20191018&ensp·&enspImportant 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.
20191015&ensp·&enspWolframite, (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.
Tungsten mines are relatively small and rarely produce more than 2000t of ore per day. Mining methods for tungsten ore are not at all exceptional and usually are adapted to the geology of the ore deposit. Most tungsten ores contain less than 1.5% WO 3 and frequently only a few tenths of a percent.
Tungsten ore occurs most frequently naturally in the form of wolframite ((Fe/Mn)WO 4) and scheelite (CaWO 4). The largest deposits of tungsten are found in China, Russia and the USA. In Austria, there is also a scheelite deposit in Mittersill in the Felbertauern district.
