The vanadium-bearing titanomagnetite concentrates in this paper were obtained from Hongge District in Panzhihua，China.The HVTMP were prepared using the gas-based direct reduction process（shaft furnace）.The compositions of the reducing gas were H2+CO+CO2+N2=100%in volume.The proportions of CO2 and N2 were both 5.00vol%，which simulated the HYL-III process.The reduction temperature was 1323 K，and the reduction time was 40 min.The reduction degree of HVTMP was as high as 95%.Details of the preparations of HVTMP have been reported in a previous study[17].The typical chemical compositions and X-ray diffraction（XRD）analysis results for HVTMP are listed in Table 1 and Fig.1，respectively.The basic phase is metallic Fe，and the metallization ratio is 91.24%.In addition，the phases of Fe Ti O3，Fe V2O4，Fe Cr2O4，Mg Ti O3，V2O3，and Cr2O3 were also detected in the reduced pellets.
