| Abstract: | A process consisting of stage grinding- stage high intensity magnetic separation-reverse flotation for HIMS concentrates was adopted to separate the iron ores with Fe grade of less than 25% from a refractory hematite of Hebei.Under the final grinding fineness of -0.074 mm 96.20%, good index on iron concentrate with yield of 25.43%, Fe grade of 66.27% and Fe recovery of 68.49% and tailing with Fe grade of 10.39% were obtained. |
