magnetic conditioning of sulfide minerals to improve

different agglomerating methods have been introduced and tested. one method that has recently received much attention is to make use of magnetic force to aggregate fine particles. a selective aggregation of fine paramagnetic particles such as sulfide minerals can be achieved in the highintensity magnetic field prior to or during flotation.
