The theory Iron content of magnetite is 72.4%. It can be called titanium magnetite or vanadium titanium magnetite when the ore contains titanium dioxide and vanadium pentoxide. Pure magnetite is not much in nature, and due to the oxidation effect of the surface, part of magnetite translates into martite and half martite.

In this paper, potassium salt roasting additives were applied to extract vanadium from vanadium–titanium magnetite concentrate. Meanwhile, the mechanisms of potassium salt roasting and acid leaching kinetics were investigated. The results indicate that potassium salt roasting additives are more efficient than sodium and calcium salt and that K2SO4 works best.

The vanadium bearing magnetite ores are typically processed through either smelting producing vanadium bearing slag (co-production) or the primary processing using a salt roasting and leaching operation, called Salt Roast process. Co-production typically involves smelting magnetite ore/concentrate during which titanium slag is eliminated while vanadium and iron ore report together …
