A theory of the dry separation of coal by density difference is proposed. The mechanism and efficiency of separation of coal particles in an air dense medium fluidized bed (ADMFB) according to bed density and the density distribution in the fluidized bed is studied.
A dry density-based fluidized bed separator was successfully utilized to beneficiate coarse particulate iron ore based on density difference. Atomized iron powder and zircon sand with size fractions of 150–75 μm and 250–150 μm, respectively, were mixed to form binary dense media for separating iron ore.
Phosphate Beneficiation. Background. Definition of "Beneficiation": This is the second step in the mining process, after removal of the ore from the ground. Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other.

Air dense medium fluidized bed (ADMFB) offers a better alternative approach for dry coal beneficiation. In recent years, there has been a rapid advancement in the understanding of fluidized bed behavior and a great deal of work has been done to make this process competitive with conventional wet beneficiation …
Processes for Beneficiation of Iron Ores Iron is an abundant element in the earth's crust averaging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be considered ore grade.
