Mineral Processing Test on Olivine Type of Vanadium-titanium Magnetite in Panxi Hongge Area

In this paper the olivine type of vanadium-titanium magnetite had been analyzed by X-ray fluorescence spectrum and X-ray diffraction spectrum to identify the raw ore mineral compositions. The main valuable metal elements in raw ore are iron and titanium,thus comprehensive utilization of iron and titanium can be considered.The main useful minerals are chlorite（from olivine and feldspar to chlorite）,amphibole and sphenite,and a small amount of pyroxene,quartz and mica present.The iron component in raw ore is mainly magnetic iron,which is concentrated in titanomagnetite,while titanium is concentrated in ilmenite.Crushing results of raw oreshow that the distribution of iron and titanium of each grain grade is relatively uniform,but the TiO₂,TFe and MFe of fine grain grade（-0.038 mm） are relatively low.Based on raw ore nature,the step grinding experiment to separate iron was carried out.The results show that after using the magnetic separation column for selection,the iron concentrate TFe grade can reach to 55.62%,the recovery rate can reach to 50. 12%. The effective recycling of iron in Olivine type of Vanadium-Titanium magnetite in Hongge can be achieved.The two-stage weak magnetic separation tailings are fed as titanium separation,and the titanium concentrate is recovered,which achieve comprehensive utilization of raw ore.
