Process Mineralogical Analysis of a Typical Vanadium Titano-magnetite Concentrate
摘要
This study is focused on the detailed investigation of the process mineralogyProcess mineralogy of a typical Vanadium titano-magnetite concentrateVanadium titano-magnetite concentrate (VTM) to efficiently utilize its valuable elements like iron, vanadium, and titanium. The investigation covers mineral phase compositionPhase composition, phase-embedding properties, and the distribution behavior of the main elements of VTM. The phase compositionPhase 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 structuresStructure and particleParticle sizes. Titanomagnetite is predominantly found in self-formed grain structuresStructure. Hematite-limonite is mainly present in crystalline structuresStructure. It also coexists with titanomagnetite or can be cemented in olivine with a sponge meteorite structureStructure. Ilmenite and magnesium spinelSpinel 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.
