Dry magnetic separation iron ore

Jan 01, 2015 An implementation of two-step concentration (afterpurification) allowed increasing the iron content in the concentrate up to 48.2%. It forces to upgrade the process of dry magnetic separation or carry it out in the liquid phase (so-called, wet separation). Fig. 5 shows the iron ore after the process of magnetic separation
