Vanadium | SpringerLink
Vanadium content in ore is low and for this reason the manufacture of ferro-vanadium is a combination of a number of metallurgical and chemical processes. Vanadium-bearing iron-titan-magnetite ore (34–38% Fe 2 O 3, 28–31% FeO, 13–14% TiO 2, 0.63–0.68% V 2 O 3, 4–10% SiO 2, 4–8% Al 2 O 3 etc.) is used for smelting pig iron …
