In this paper, in order to obtain high efficiency utilization of Panzhihua vanadium-bearing titanomagnetite concentrate, high grade of concentrate with FeT57.25% was enriched by fine grinding and twice of magnetic separation. Then the titanomagnetite pellets was reduced by graphite at 1250 C to reach high metallization degree above 80%. Melting and separation behavior of metallization pellets was performed to obtain metallic iron and titanium slag. The results showed that the effective separation of metal iron and slag could be obtained in which over 95% Fe was transferred into metal phase and over 93% Ti was enriched in slag in graphite crucible at 1500C and melting 60 min. the complete separation of slag and metal phases was achieved. The main components in the solid slag are geikielite(MgTi2O5), perovskite(CaTiO3), magnesia-alumina spinel and aluminum silicate, magnesium silicate. In the solidslag, the content of TiO2 reach to above 55%.
