removal of fines for the spiral in chromite beneficiation

Chrome Ore Beneficiation Technical Process_BAILING® Machinery

Chromite (FeCr2O4), specific gravity 4.3-4.6, hardness 5.5-7.5, is the only useful mineral for chrome ore beneficiation, which also can be used as high grade refractory. It has weak magnetism. Generally the harangue minerals have iron ore, which make trouble for strong magnetic separation.
