Vanadium Mining

Major deposits of vanadium were discovered in central Arkansas by Union Carbide’s Western Exploration Group in the 1960s. Vanadium orebodies are found in two isolated igneous intrusive complexes in the Ouachita Mountains of Arkansas: the Potash Sulphur Springs (now Wilson Springs) complex located in Garland County and the Magnet Cove complex in Hot Spring County. The Wilson Springs vanadium deposits were the first to be mined solely for vanadium in the United States. The major use of vanadium is as an alloying metal in iron and steel (ferroalloy). Small amounts of vanadium added to iron and steel significantly increase its strength, improve toughness and ductility, and reduce weight, making it suitable for structural and pipeline steel. Vanadium also increases high-temperature …
