The extraction of vanadium from titanomagnetites and other sources
Vanadium does not form concentrated deposits like other metals such as copper, nickel or zinc. It is widely dispersed in the Earth's crust, with V 3+ replacing Fe 3+ or Al 3+ in a number of minerals. Vanadium as V 3+ can substitute for Fe 3+ in magnetite (Wenk and Bulakh, 2004); vanadium(III) and iron(III) ions have near identical ionic radii in octahedral sites of …
