Vanadium processing, preparation of the metal for use in various products.. Vanadium (V) is a grayish silver metal whose crystal structure is a body-centred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to high-strength low-alloy (HSLA) steels and, to a lesser extent, in tool steels and iron and steel castings.Vanadium element extractionmethods – smelting, leaching,,MINING AND PROCESSING : The major ores of vanadium are patronite (VS 4), carnotite [K 2 (UO 2) 2 (VO 4)3H 2 O], and vanadinite [Pb 5 (VO 4)3Cl].Since much of the vanadium present in the 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, the ore deposits,Making Vanadium | Vanitec,Coproduct steelmaking slag resulting from the processing of titaniferous magnetite ore supports about 59% of global vanadium.
