the performance of the full scale reflux classifier

Iron Ore Beneficiation

We have recently achieved remarkable separation performance over the range 01 mm to 0 mm by applying the REFLUX™ Classifier to a well liberated haematite ore, with grades in excess of 65 % and Fe recovery reaching 80 % across the full size range, with the recovery approximately 50 % below 0020 mm and greater than 90 % above 0038 mm.
