RECENT DEVELOPMENTS IN PRECONCENTRATION …

ore (e.g. grade in the heavy products) are not always considered for preconcentration. Compared to the cyclone which is limited by the crowding effect in the apex, the multi-stage separation in the Condor unit provides larger sinks product capacity. The primary advantages of using a dense medium cyclone arise when only a single stage
