Abstract: Research on beneficiation tests for a certain iron ore from South Africa was carried out. The experiments showed that under grinding fineness at -0.074mm 70% and magnetic intensity at 79.557KA/m, the iron concentrate with Fe grade of 65.96%, the yield of 88.46%, and the recovery of 98.30% could be obtained by two-stage magnetic separation.

Key words: Magnetite ore, Grinding fineness, Magnetic separation
