Evaluation of Ilmenite as Dense Medium for Dry Coal …
Published work on dry dense medium fluidized beds has mainly used magnetite and fine coal to make up the dense medium. Magnetite is used to achieve the required cut densities, but its recovery and reuse are problematic because it attaches to the surface of the coal and discard material, and its surfaces become contaminated.
Development of Air Dense Medium Fluidized Bed Technology For Dry
Dry beneficiation of coal offers a better alternative approach for cleaning coal. An overview on the development of separation technology for beneficiation of coal using dense medium fluidized bed system is described. A theory of the dry separation relevant to coal beneficiation by density difference has been highlighted.
