COMBINED POLYMER AGGREGATION OF FINE PARTICLES OF WEAK MAGNETIC M1NERALS IN EXCEEDINGLY FEEBLE MAGNETIC FIELD

Polymer flocculation is always recognized as an effective method of selective aggregation of fine particles of weak magnetic minerals. In our research work, a combined polytner aggregation in an exceedingly feeble magnetic field (about 0.006T) has been realized by introducing magnetic aglomeration into polymer flocculation process, which apparently strengthened the polyrner flocculation process and improved the aggregation ability and selectivity of the process. Subsequently, a phenomenon model and an energy model and mechanism of the combined aggregation have been established.
