Tungsten metallurgy is the technology that extracts the tungsten metal from tungsten ore raw materials. In 1781, the Swedish chemist C.W. Scheele separated a new oxide from scheelite and named it tungstic acid. In 1783, the Spanish chemists J.J. Elhuyar and F. Elhuyar, who were brothers, separated tungstic acid from wolframite.
