Vanadium minerals of economic importance include patronite (VS4), vanadinite (Pb5(VO4)3Cl) and carnotite (K2(UO2)2·3H2O. The major commercial source of vanadium is vanadium-bearing magnetite found in ultramafic gabbro bodies. The metal is hard, ductile, malleable and not brittle [694,695]. It is resistant to corrosive attack by alkalis and sulphuric and hydrochloric acids [696].

Determination of vanadium at trace levels is important for an understanding of its geochemical and biological effects as well as for monitoring of environmental pollution.[1] Vanadium is the fifth most abundant transition metal in the earth crust.[2] It originates from primary sources such as ores, concentrates, metallurgical slag, and petroleum residues.[3] It is also found at rather high concentrations in some freshwaters and is listed as a metal of concern by the United States Environmental Agency (USEA).[4] Vanadium is never found in its pure state, and it is one of rare earth elements. It occurs in combination with over 50 different minerals such as carnotite (K2(UO2)2(VO4)2.3H2O), vanadinite (Pb5(VO4)3Cl), and patronite (VS4).[5]
