Since the early 1900s, vanadium has been used as an alloying element for steels and iron. In 1905 Antenor Riza Patron discovered a large asphaltite deposit containing rich vanadium ores in Mina Ragra, Peru. Two years later, the American Vanadium Company produced ferrovanadium on a commercial scale for the first time.

Mineral Resource of the Month: Vanadium

The vanadium mineral, roscoelite, was named in honor of Roscoe's work. Vanadium is only found in nature in chemically combined forms. It is extracted from vanadiferous ores, slags and residues and converted into vanadium pentoxide or xide. Most pentoxide is converted into ferrovanadium, an iron-vanadium alloy.
