ABSTRACT. Dry processing options, involving the use of a circulating air classifier and thermal roasting (advanced microwave-assisted magnetizing roasting), followed by magnetic separation using an Induced Roll Magnetic Separator (IRMS), were evaluated for upgrading low-grade hematite-goethite iron ore fines.
A water-medium tapered column separation bed and an active pulsing air classifier were utilized to achieve an effective classification of materials with different particle size distribution. The experimental results indicate that the metal concentrates could be recovered and recycled efficiently by the effective physical beneficiation flowsheet.

the high-throughput operation required three 26-foot Whirlwind® Air Classifiers per production line that could remove beneficiated Fe fines at 120-mesh, 200-mesh and 325-mesh after the fine grinding stage. The refined iron from the air classifier was conveyed to the next stage of the beneficiation process: the magnetic separator rolls.
The air flow rate was measured with romameters and could be regulated by valves to form the minimum fluidization condition and the designed working conditions for coal beneficiation. Even with a porosity rate of 2% and a thickness of 20 mm, the pressure drop of the air distributor was not enough to ensure the fluidization uniformity in the bed ...
