The majority of vanadium in titanomagnetite deposits occurs as V 3+, with a small amount of V 4+. X-ray absorption near edge structure spectroscopy (XANES) of seven titanomagnetite samples from different locations has shown that only approximately 2–17% of the vanadium was present as V 4+ ( Balan et al., 2006 ).
