Tungsten compounds are often used as industrial catalysts. Its largest use is in tungsten carbide, a wear-resistant metal used in metalworking, mining, and construction. [22] About 50% of tungsten is used in tungsten carbide, with the remaining major use being alloys and steels: less than 10% is used other compounds. [23]
Tungsten ore is a rock from which the element tungsten can be economically extracted. The ore minerals of tungsten include wolframite, scheelite, and ferberite. Tungsten is used for making many alloys. Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions. [1]
The Sangdong Mine, which has one of the world's largest tungsten deposits, is poised to produce up to 15% of the global tungsten supply once fully operational. The mine's tungsten grade of 0.45-0.50%, more than twice the global average of 0.18% [7], ensures its competitiveness. Almonty's development efforts at Sangdong also aim to address ...

For the production of the tungsten heavy alloy, binder mixtures of nickel and iron or nickel and copper are widely used. The tungsten content of the alloy is normally above 90%. The diffusion of the binder elements into the tungsten grains is low even at the sintering temperatures and therefore the interior of the grains are pure tungsten. [18]
