What Is Coal Preparation? Energy.gov
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 preparation, a uniform product is achieved.

Gravity Concentration an overview ScienceDirect Topics
Gravity separation, for instance, may be used to reject a major portion of the gangue, as it is a relatively cheap process. It may not, however, have the selectivity to produce the final clean concentrate. Gravity concentrates therefore often need further upgrading by more expensive techniques, such as flotation.
