Coal Preparation - an overview ScienceDirect Topics

Coal preparation processes, which are physical processes, are designed mainly to provide ash removal, energy enhancement, and product standardization (Elliot, 1989). Sulfur reduction is achieved because the ash material removed contains pyritic sulfur.

Coal preparation for conversion processes -

1981-9-1  It is emphasized that it is vitally important that the development of the new conversion processes is not carried out in isolation from an understanding of both the mining and preparation of coal for it is the cost effectiveness of the total operation, mining, coal preparation, and conversion, that is important, and not that of any one aspect individually.

What Is Coal Preparation? - Energy.gov

2013-2-21  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.
