The dry separation methods for coal beneficiation have been regaining attention in the past decades. A number of improved or newly designed devices have been developedone of them is a negative pressure pneumatic separator NPPS. The said method of separation is based on the differences in the physical properties between coal and gangue minerals such as the grain density size and shape.

US4408999A Coal and oil shale beneficiation process

Coal oil shale and similar carbonaceous solids are beneficiated by subjecting the solids to electromagnetic radiation having a frequency between about 0.1 MHz and about 10 5 MHz in the presence of an aqueous acid solution. The electromagnetic energy enables the acid to solubilize a substantial portion of the mineral matter contained in the solids at low temperatures and pressures

Coal Beneficiation an overview ScienceDirect Topics

Coal beneficiation or coal preparation as it is also termed refers to the processes through which inorganic impurities are separated from raw mined coal thereby providing improved combustion characteristics to the fuel produced. The separation processes used are primarily based on exploiting the physical differences between the organic i.e. coal and inorganic i.e. ash components.
