The extraction of vanadium from titanomagnetites

2020-1-15  Vanadium is typically recovered as vanadium pentoxide or ferrovanadium metal at the mine site. Vanadium pentoxide can be further purified to produce vanadium chemicals and battery electrolytes, or reduced to ferrovanadium. Ferrovanadium is a mixture of iron and vanadium used in the steel industry for the production of vanadium steel.
