Abstract:The effect of aluminum powder on the carbothermal reduction process of vanadium-titanium magnetite concentrate was studied. The results show that the addition of aluminum powder can promote the rate of carbothermic reduction of vanadium-titanium magnetite concentrate. During the reduction process, aluminum powder replaces carbon as a reductant to participate in the reduction reaction, which releases a large amount of heat to cause local high temperature around it, thereby promoting the progress of the carbothermic reduction reaction and promoting the accumulation of new metal iron. The addition of 1% aluminum powder can slightly improve the separation of slag and metal; when the amount of aluminum powder added is more than 2%, the fluidity of the slag becomes difficult due to the formation of TiC, and the separation effect of slag and metal is deteriorated.
