vanadium ores processing

vanadium processing Britannica
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.

Processing of vanadium: a review - ScienceDirect
Abstract. Vanadium is an important by-product that is used almost exclusively in ferrous and non-ferrous alloys due to its physical properties such as high tensile strength, hardness, and fatique resistance. Vanadium consumption in the iron and steel industry represents about 85% of the vanadium-bearing products produced worldwide.

Making Vanadium Vanitec
Ferrovanadium is available in alloys containing 40%, 60% or 80% vanadium. The 60% and 80% grades are mostly produced by the aluminothermic reduction of vanadium oxides in the presence of steel scrap or by direct reduction in an electric furnace. The 40% grade is produced from slag and other vanadium products by the silicon reduction process.
