INFLUENCE OF WATER MAGNETIZATION ON THE FLOATABILITY OF HEMATITE AND ITS MECHANISM

The paper describes the relationship between a floatation ratio,medium's surface tension and collector's dosage and medium's pH and their working mechanism after the floatation medium water is magnetized.The results show that the surface tension of oleic acid water can be lowered by magnetization,causing the floatation ratio of hematite increased.We think that this change is made by magnetization by which water molecules average moving energy is added and chromatic dispersion force,induced force and orientation force among water molecules are weakened and the polymeric state of water molecules is acted,thus making the solution of oleic acid in the water increased.Therefore,the concentrate of the bi-polymer of ion of oleic acid molecules is increased which is an effective surface activator and has important role on hematite's floatation.
