mineral processing vanadium

Vanadium processing | Britannica.com

The important vanadium minerals are patronite (VS4), carnotite [K2(UO2)2(VO4)2], and vanadinite, [Pb5(VO4)3Cl]. Ore deposits mined solely for vanadium are rare because much of the vanadium in igneous rocks occurs in the relatively insoluble trivalent state, substituting for ferric iron in ferromagnesium silicates,...
