2020-10-20  Ores. The important vanadium minerals are patronite (VS 4), carnotite [K 2 (UO 2) 2 (VO 4) 2], and vanadinite, [Pb 5 (VO 4) 3 Cl]. 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, magnetite (an iron ore), ilmenite (a titanium ore), and chromite.
