Tungsten is a non-ferrous metal and an important strategic metal. Tungsten ore was called "heavy stone" in ancient times. In 1781, the Swedish chemist Carl Wilhelm Scheele discovered scheelite and extracted a new element acid-tungstic acid. In 1783, it was discovered by the Spanish Depuria that wolframite also extracted tungstic acid.
