tungsten the mineral

The extractive metallurgy of tungsten has developed since 1847, and has achieved a great progress. Until the 1950s, the tungsten metallurgy was largely empirical and mainly based upon patents, even though almost all the currently available methods of treating tungsten ores have been proposed at …

Tungsten processing | Britannica

Tungsten is mostly obtained from the minerals scheelite and wolframite. Tungsten is not refined by smelting or through any other method through which other metals are refined since it has the highest melting point above any other metal. The surface mining methods are used when the tungsten minerals are found in the earth's surface where underground digging is not required.
