Experimental Research on the Iron Separation from an Ultra Poor Iron Ore

Abstract:

Test was made on separating iron from a ultra-low-grade vanadium titanium 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 raw ore is treated by permanent dry magnetic separator with low intensity magnetic separation at 12～0 mm size，qualified tailings of about 20% yield can be discarded．The coarse concentrate is grounded in two stages. With the first stage grinding size being 45% -200 mesh and the second stage，75% -200 mesh，and then treated by two stage low intensity magnetic separation．As a result，an iron concentrate with a TFe grade of 65.80%and an iron recovery of 47.74%can be achieved．
