STUDY OF THE INFLUENCE OF MAGNETIC PARAMETERS ON THE FLOTABILITY OF HEMATITE IN WATER-SYSTEM TREATED BY MAGNETIC FIELD BASED ON ORTHOGONAL TEST

Based on orthogonal test L81 (340), the paper describes the influuence and it's significance ofvariance of four magnetic parameters (magnetic density, water velocity through the field, magnetizing time andfield configuration) on the flotability of hematite in water-system treated by magnetic field. The test resultsshow that water-spotem treated by magntic field may increase the efficiency of notation for hematite collected byoil acid and there are notable interactions between four parameters.
