| Abstract: | Experimental study was carried out to beneficiate a lean magnetite ore from Yunan Province with TFe grade of 22.35% and magnetic iron (mFe) content of 15.58%. Based on preconcentration tests with varied feed size and contrast tests of multiple processes, a suitable dressing flowsheet is proposed. It is shown that a flowsheet consisting of sequentially coarse fraction preconcentration, grinding, low intensity magnetic separation (LIMS), gravity separation, regrinding and LIMS processes, can produce an iron concentrate grading 65.70% TFe at 70.28% recovery with the yield of 23.89%. |
