ADMFB is an efficient coal cleaning device in the size of 6-50mm but has not a good performance in the size finer than 6mm that is important due to considerable fraction of -6 mm particles in run of mine coal. In this research, dry gravity concentration of coal in the size ranges of 4-6.3 mm, 2-4 mm, 1-2 mm and 0.5-1mm was evaluated.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
