Taking vanadium-titanium magnetite electric furnace slag as the research object, the authors systematically studied chemical composition, mineral composition, mineral and element distribution characteristics of the slag by means of chemical analysis,X-ray diffraction analysis and electron microprobe analysis. The results show that 94.74% Ti exists in anosovite, Mg and Al mainly occur in the form of magnesia alumina spinel, calcium and silicon are mainly in the form of diopside, while iron is dispersed in various minerals. The valuable mineral is anosovite, which is mainly disseminated with diopside, and partly distributed in spinel. Besides, some of Mg and Al occur in anosovite in the form of isomorphous admixture; as a result, the content of TiO₂ in anosovite is only 82.04%. The result can provide scientific basis for the comprehensive utilization of vanadium-titanium magnetite electric furnace slag.
