Pure tungsten is a shiny white metal and in its purest form is quite pliant and can easily be processed. However, it usually contains small amounts of carbon and oxygen, which give tungsten metal its considerable hardness and brittleness.
Tungsten occurs in the natural state only in the form of chemical compounds with other elements. Although more than 20 tungsten bearing minerals are known, only two of them are important for industrial use, namely wolframite and scheelite.
W Resources Plc (LON:WRES) engages in the exploration and development of tungsten, tin, copper, and gold properties.
