Coal Beneficiation via the Tapered Fluidized Bed Using Magnetite
A gas–solid fluidized bed using magnetite particles is an effective methodology for coal beneficiation in the field of dry coal cleaning. Broadening the size range of magnetite used in the bed decreases medium preparation cost. In this study, a tapered fluidized bed was used to investigate a magnetite particle size range of −0.5 + In our previous studies, we demonstrated the performance of novel superfine crusher and pneumatic planar magnetic separator as energy-efficient technologies for dry processing of magnetite ores.

DRY MAGNETIC SEPARATION OF MAGNETITE ORES ScienceGate
The optimum grade that could be obtained from single-stage dry magnetic separation was 35.52% Mn, and with a Mn:Fe ratio of 1.77, and 44% Mn recovery in the case of sample 1; whereas, a 33.75% Mn grade, with a Mn:Fe ratio of 1.66 at Mn recovery of 44% was reported for Sample 2. It was observed that both samples had a similar input chemistryIn Brazil, Sierra Leone and Vietnam, high silica run of mine (ROM) ores are effectively washed and scrubbed to produce high quality metallurgical grade bauxite. Thanks to the generally homogeneous nature of washed ore, combined with low kaolinite, goethite, organic carbon and high gibbsitic alumina content, these bauxites are the preferred ore Bauxite Beneficiation: An Approach to Value Addition in Mining
