Tungsten (W) Ore | Minerals, Occurrence » Geology Science
Tungsten ore refers to the natural rock or mineral containing tungsten in its compound form. Tungsten is commonly found in nature in the form of tungstates, such as scheelite (CaWO4) and wolframite [ (Fe,Mn)WO4].Web
Tungsten Metallurgy | SpringerLink
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.Web
