Titaniferous magnetite (titanomagnetite) resources contain economically significant reserves of vanadium and iron as well as titanium. Titanomagnetite is a primary source of vanadium– about 88% of the world’s vanadium is extracted from titanomagnetite (Fischer, 1975; Roskill, 2010; Zhong et al., 2014). Vanadium is recovered from titanomagnetite by two main processes – the vanadium and steel
