Vanadium-bearing titanomagnetite (VT) is a polymetallic intergrowth iron ore that owns a wide distribution throughout the world such as Russia, China, North Africa, and America etc.1) In VT, there are various valuable elements including iron, titanium, vanadium, and chromium which are typical strategic resources due to its extensive application in metallurgy, chemical industry, and aerospace etc.2–4) Based on the mass fraction of Cr2O3, VT is classified into two categories: ordinary VT and high chromium vanadium– bearing titanomagnetite (HCVT), and HCVT has a higher comprehensive utilization value.2) At present, VT is smelt in blast furnace (BF) but the recovery rate of Fe, V, and TiO2 is only reach 70%, 39% and 13% respectively.5–7) Recently, the technology of direct reduction followed by melting separation applying to dispose special metallurgical resources has attracted increasing attention.8–11) Jun et al.8) studied the carbothermal reductionmelting separation process for copper slag.
