Process Mineralogical Analysis of a Typical Vanadium Titano-magnetite Concentrate

This study is focused on the detailed investigation of the process mineralogy of a typical Vanadium titano-magnetite concentrate (VTM) to efficiently utilize its valuable elements like iron, vanadium, and titanium. The investigation covers mineral phase composition, phase-embedding properties, and the distribution behavior of the main elements of VTM. The phase composition of VTM consists of 84.11% titanomagnetite, 6.52% hematite-limonite, 1.41% ilmenite, 3.87% olivine, and 3.31% alumina. The ore of VTM consists of individual metallic mineral grains and intergrowth grains with diverse structures and particle sizes. Titanomagnetite is predominantly found in self-formed grain structures. Hematite-limonite is mainly present in crystalline structures. It also coexists with titanomagnetite or can be cemented in olivine with a sponge meteorite structure. Ilmenite and magnesium spinel exist as exogenous crystals within the titanomagnetite. Pyroxene, olivine, silicate, and clay minerals occur in different forms and intergrowths with metallic minerals. Iron and titanium elements in VTM exist mainly in the forms of ilmenite and titanomagnetite, while vanadium elements occur in isomorphism forms within these mineral phases.
