Vanadinite is a secondary mineral in the oxidized zone of lead bearing deposits. Almost always found in the oxidation zone of lead deposits in arid climates resulting from the alteration of vanadiferous sulphides and silicates of the gangue and wall rocks.
Vanadinite is one of the main industrial ores of the metal vanadium and a minor source of lead. About 80% of vanadium produced is used as a steel additive. Vanadium steel alloys are very tough, used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant. Vanadium (V) oxide is used as a pigment for ceramics and glass, as a catalyst and in producing superconducting magnets.
