Vanadium consumption in the iron and steel industry represents about 85% of the vanadium-bearing products produced worldwide. The ubiquitous vanadium is employed in a wide range of alloys in combination with iron, titanium, nickel, aluminum, chromium, and other metals for a diverse range of commercial applications extending from train rails, tool steels, catalysts, to …
Ilmenite is also known to host vanadium (Xu et al., 2017). Hence, iron and titanium deposits are a major source of vanadium (Gupta and Krishnamurthy, 1992, Dill, 2010). Likewise, much of the vanadium in titanomagnetite ores is associated with magnetite, with ilmenite containing relatively small amounts of the vanadium present in such ores.
The vanadium in these deposits is associated with specific minerals knowns as magnetite, an iron-oxide, and ilmenite, an iron-titanium oxide, and also a titanium oxide known as rutile. They typically grade between 0.2 and 1% V 2 O 5 with higher grade deposits such as the Bushveld attaining grades over 2% V 2 O 5 .
