Tungsten processing | Britannica

In 1783 the Spanish chemists Juan José and Fausto Elhuyar obtained metallic tungsten by the reduction of its oxide with carbon; it was named wolfram (hence its chemical symbol, W) for the mineral wolframite, from which it was extracted. In 1847, Robert Oxland patented in Britain his manufacturing process for sodium.
