Abstract: Beneficiation tests on Hongge low-grade vanadium-titanium magnetite of Panxi are carried out by the process of high-pressure roller mill-wet magnetic separation for coarse ores-iron concentration with stage grinding and weak magnetic separation for run-of-mine, and the titanium concentration process of low intensity magnetic separation-high intensity magnetic separation-flotation at the iron concentration from tailings. Then, iron concentrate with Fe grade of 57.41% and recovery of 52.88%, and titanium concentrate with TiO2 grade of 47.87% and TiO2 recovery of 39.31% are achieved. The test results show that the grinding volume in iron and titanium separation process are lowered by 34.18% and 10.19% respectively by adopting the high-pressure roller mill.
