Classification of tungsten ores; Tungsten ores; Tungsten does not occur naturally in its pure metallic state; rather, it is found in several ores, but only two kinds of tungsten-bearing mineral rocks, called wolframite and scheelite, are mined commercially. Wolframite accounts for about 70% of the total tungsten resources in the world, and scheelite accounts for about 30%.

Tungsten was first found in the Ore Mountains of Central Europe in the Middle Ages during the process of tin reduction. However, at that time it was considered to be an unwanted accompanying element. The tungsten ore facilitated slag formation during the reduction of tin and consequently impaired the yield.

The history of tungsten dates back to the Middle Ages (mid 16th century) when tin miners in the Ore (Erz) Mountains of Saxony-Bohemian Erzgebirge in Germany noticed that a certain mineral often accompanied its tin ore. The miners found that this mineral reduced the tin yield during the smelting process and increased slagging.
