2009· 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.Beneficiation of coal is a vitally important process in reducing environmental hazards associated with combustion of run-of-mine coal. To scale down energy consumption and improve on environmental impacts of wet cleaning processes
