Centrifugal high gradient magnetic separation of fine

Nov 10, 2017· Abstract. High gradient magnetic separation (HGMS) has been an effective method for the concentration or removal of fine para-magnetic particles from suspension, but its powerful magnetic capture to magnetic particles results in the mechanical entrainment of non-magnetic particles in magnetic product, and thus reduces the separation selectivity. HGMS in centrifugal field (CHGMS) is proposedCited by: 16

Effect of selective coating of magnetite on improving ...

Apr 01, 2020· According to the results and discussions in this study, the magnetic separation of ilmenite from titanaugite was achieved by the assistance of magnetic coating. After treated by magnetic coating, the recovery of ilmenite was increased by approximately 36% and the TiO 2 grade enhanced 2% in the magnetic separation of mixed minerals. These results were attributed to the enlarging magnetism difference between ilmeniteCited by: 5
