Abstract: Test was made on separating iron from a low grade Vanadiferous titano-magnetite ore by a process of tailing discarding at a coarser size, staged grinding and staged low intensity magnetic separation. The results show that when the run-of-mine ore is treated by double-layered roll type magnetic separators including low and high intensity magnetic separation at 10~0 mm size, qualified tailings of about 9% yield can be discarded, with an iron loss in the coarse tailing being only about 3%. The coarse concentrate is grounded in two stages, with the first stage grinding size being 50% -200 mesh and the second stage, 85% -200 mesh, and then treated by two stage low intensity magnetic separation. As a result, an iron concentrate containing 57.08% iron and 11.92% TiO₂ and having an iron recovery of 53.16% can be achieved.
