Solid State reduction and electric furnace smelting of V-Ti magnetite concentrate

Researches on solid state reduction and electric furnace smelting technology of V-Ti magnetite concentrate from Panxi area of China were investigated. The results showed that additive and pre-oxidation processing could significantly accelerate the reduction process. The pre-reduction product was smelted tinder the conditions of basicity (CaO/SiO(2)) in the slag 1.2, the content of MgO 6%, the content of Al(2)O(3) 9%. The pig iron with 96.90% Fe grade, 99.47% Fe recovery, 0.52% vanadium grade and 80.20% vanadium recovery was obtained. Titanium was enriched in slag with TiO(2) grade of 66.13%, which can be used to produce titanium, dioxide. This study not only improved the efficiency of pre-reduction electric furnace smelting, but also achieved comprehensive utilization of the V-Ti magnetite concentrate.
