| Abstract: | The effects of magnetic field intensity and grinding granularity on magnetic separation index of Fe were investigated. Preliminary classification of ore was carried out followed by magnetic separation to remove part of the gangue. A mineral processing flowsheet of coarse grinding followed by magnetic separation and then regrinding and concentrating of coarse concentrate was performed, increasing the productive capacity of the raw ore and lowering the grinding cost. Iron concentrate of 65.54? with the recovery of 94.11% was obtained. |
