Abstract

In recent years, a new process of “direct reduction-electric furnace smelting separation” has been put forward and developed for recovering the iron, vanadium, titanium and chromium to make full use of the chromium-bearing vanadium titanium magnetite. In the present work, FactSage, one of the most frequently-used thermodynamic calculation software, was used to calculate the migration of Fe, V, Cr and Ti with different nC/nO (mole ratio of carbon and oxygen). The calculation results indicate that the recoveries of Fe, V and Cr increase with increasing nC/nO and temperature respectively. In addition, the recoveries of Fe, V and Cr are up to 90% when the nC/nO value is more than 1.15.
