Tungsten - Almonty Industries

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. Foam would appear on the surface of the tin melt and a heavy slag ...
