What Is Coal Preparation Coal preparation is the removal of undesirable material from the Run-of-Mine ROM coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal
feed coal is reduced from 42 to 34 and to 24 respectively. Total project cost of such plant including cost of coal washery and AFBC for using washery rejects at ash content at 42, 34, 24 is likely to be cheaper by 5, 8 and 10 respectively. Generation of 15 to 18 MWe by AFBC is an extra benefit. Larger gains may be
