Experimental Study on Magnetic Separation of Oolitic Hematite Ore

Abstract:

To enhance effective use of resources, we use magnetic separation method on the experiment study of a refractory oolitic hematite ore. Research showed that: the grade of raw ore (TFe) was 47.44%, and magnetic iron grade (MFe) was 28.59%. Through magnetic separation experiment, three-step magnetic separation process was chosen. The magnetic field intensity (MFI) of three magnetic separation processes was 1200Oe800Oe400Oe, respectively. After first magnetic separation, the preliminary concentrates was reground to fineness of 87% (-500 mesh). Under the optimal experiment conditions, an iron ore concentrate with grade of 61.11% and a good recovery of 44.35% was obtained.
