A low grade vanadium-titanium magnetite contains 17.92% of TFe（total Fe） and 6.19% of TiO2.Using the process of tailings discarding by dry pre-concentration followed with staged grinding and concentration,an iron concentrate containing 60.57% of TFe and 7.89% of TiO2 can be obtained,and recovery rate of Fe in the whole process is 49.34%.After tailings discarding at a coarser size,Fe,V,Ti,Cr,Sc,Co and Ni are mainly concentrated in the primary concentrate.Through wet magnetic separation,V and Cr in the iron concentrate are enriched apparently,while Co and Ni are concentrated in some degree,with Sc mainly in the weak magnetic separation tailings.S in the dry tailings is of low content but is enriched in the iron concentrate to a certain extent.
