Contained in the titano-magnetite ore is a persistent fractional percentage of vanadium. The total reserves of titanium and vanadium in these iron ores must be very large. It is obvious, therefore, that the ores of the Bushveld igneous complex occupy a prominent place in the world's mineral resources.
