Abstract: High chromium vanadium-titanium magnetite pellet with metallization rate of 95%， obtained from gas-based shaft furnace reduction， was used for melting and separation in a high-frequency induction furnace. Through the three factors with three levels orthogonal test， the influences of melting temperature， melting time and binary basicity on the recovery of iron， vanadium， chromium and titanium were studied. Then， the results were analyzed by comprehensive weighted scoring method， and the iron containing V and Cr and the slag bearing Ti are obtained finally. The results show that the optimal parameters of melting and separation for high chromium vanadium-titanium magnetite pellet are the binary basicity of 1.1， the temperature of 1650℃ and the time of 45min. The effect of the melting index are as follows:binary basicity，melting temperature and melting time.Moreover， the effect of binary basicity on the recovery rate was studied. It was indicated that all the recovery rate increases first and then decreases with the rising binary basicity. The rational binary basicity is 1.1.

Key words: high chromium vanadium-titanium magnetite, electric melting separation, orthogonal test, comprehensive weighted scoring method
