Abstract. Dry beneficiation of fine coal was investigated using air fluidization in a vibrating air table. A systematic study based on a response surface method of experimentation revealed the features of separation. The ash content of the − mm coal feed was reduced from % to % with % mass yield of the clean coal.

Beneficiation of coal (separation of ash minerals from coal) is generally achieved using the waterbased processes. Most of the preparation plants utilizes gravitybased processes, such as jigs, heavy media vessels, cyclones, spirals, etc., for particles down to a size of 28 mesh ( mm). The finer size (minus 6 mm) is beneficiated either by ...

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 developed—one 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.
