Experimental Research on Deep Reduction and Grinding Separation of Low Ti-bearing Vanadium-titanium Magnetite

Experimental research on deep reduction and grinding separation of a certain low Ti-bearing vanadium-titanium magnetite was conducted.The results show that the critical conditions for inhibiting the reduction of vanadium are reduction at 1 050℃ for 10 h.The reduction of vanadium-titanium magnetite can be enhanced by additives and extension of reduction time.Borax can efficiently promote the reduction of the vanadium-titanium magnetite,and the metallization rate of product reaches 98.21% with 3% borax added.However,inhibitory effects on reduction were observed with CaF₂ in the experiments.Low intensity magnetic separation and deep grinding are beneficial to separate Fe and V.
