Dry beneficiation of the coal was attained within the ADMFB, in varying degree, for each of the variables listed above. For a theoretical product of 75 bed volume (or the top 3 bed layers), ash yields obtainable are recorded to vary between 13 and 17.6 with a corresponding mass yield percentage range of 27.6-34.2.

Jun 14, 2011 The increased mechanization in the underground coal-mining industry has increased the volume of fine size coal and waste (refuse) in the mined coal. Processing of run-of-mine (ROM) coal is generally done using water away from mine and in some cases the coal has to be transported a long distance to the preparation plant. Dry processing of coal can be economical as it will not utilize water.
