Analysis of Vanadium in Vanadiferous Titaniferous Iron Ores

Rapid screening method for the determinations of vanadium as recommended by U.S.G.S. has been verified and made use of in screening the samples. The verification was limited to 0.1% and above. The separation between titanium, iron and vanadium was effected by pouring the hot 0.1 N sodium hydroxide into acid extract. The filtrate has been tested for vanadium. Excellent reproducible results have been obtained, thereby establishing a standard procedure for determining low percentages of vanadium in titaniferrous iron ores.
