Study on the Compositions and Structure Characteristics of a Vanadium-titanium Magnetite from Panxi Region

The chemical analysis,spectral analysis,X-ray diffraction phase qualitative analysis,optical microscope,scanning electron microscope and MLA analysis were employed to systematically study the chemical and mineral compositions of a vanadium-titanium magnetite(V-Ti magnetite) from Panxi area in this paper.The results indicate that the V-Ti magnetite is mainly consisted of iron,titanium and vanadium,etc.,with about 31% TFe,11% Ti O₂ and 0.5% V₂O₅ satisfying the industrial utilization standards overall.Besides the iron,titanium and vanadium all of which are the major components for utilization of this ore,a lot of beneficial associated elements(e.g.chromium,manganese,cobalt,nickel and copper,etc.) are contained in the V-Ti magnetite.The main metallic minerals in this ore are titanium-magnetite(43.09%~45.09%) and ilmenite(11.67%~13.17%) which can be used for industrial beneficiation of iron concentrate and titanium concentrate,respectively.Moreover,the V-Ti magnetite also contains some sulfide minerals such as pyrite,galena,sphalerite and chalcopyrite,etc.which can form the sulfur cobalt concentrate after beneficiation.The V-Ti magnetite is mainly of disseminated structure with subhedral-anhedral,embedded,sideronitic,metasomatic relict and solid separation textures.The results confirm the materials basis for the comprehensive utilization of this vanadium-titanium magnetite and make clear the structure characteristics of this ore,which provides important basic information for the establishment of beneficiation processes of this ore.
