What Is Coal Preparation Coal preparation is the removal of undesirable material from the RunofMine 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 preparation a uniform product is achieved 12 A process for cleaning coal solids which comprises a subjecting said coal solids to a gravimetric separation carried out in a liquid medium at a specific gravity between about 15 and about 19 thereby separating said coal solids into a first low density fraction and a first high density fraction Gravity concentration is an established unit operation in mineral processing where the separation of target minerals from gangue minerals is based on the difference in their specific gravity Feasibility of gravity concentration is simplistically calculated using the concentration criterion CC which can be expressed as follows
