Abstract
An existing scheme of vanadium production from low-titanium magnetite concentrates is energy-consuming and associated with loss of valuable elements, e.g. titanium. The present work investigates the possibility of obtaining products, which are different from the processing using the conventional technological scheme, for further development of an energy-efficient and wasteless technology.
A magnetite concentrate containing titanium and vanadium oxides was reduced with coal in a vertical furnace. The effect of temperature was studied at 1000, 1100 and 1200 oC. After reduction the metallized product was melted to separate metallic Fe from slag containing V2O5 and TiO2. The phases obtained during reduction and smelting were studied using XRD and SEM analysis. The concentration of V2O5 and TiO2 in a final product has increased in comparison with the initial magnetite concentrate with minimum transfer to metal.
Keywords: magnetite coal reduction, vanadium oxide, titanium oxide.
