Coal Beneficiation - an overview ScienceDirect Topics

Size separation processes are the simplest to implement. These processes exploit distinct difference in sizes between coal and ash particles. If, for example, the coal to be processed is coarse while the ash is fine, then efficient separation can be achieved by a simple screening at the appropriate size.

Coal cleaning process - Genesis Research Corporation

By removing coarse clean coal and refuse, only the middling fraction need be comminuted for further processing as fine particle coal. Thus, the process has the advantages of reducing the load on fine particle coal separation equipment, minimizing the cost of comminution and minimizing the amount of fines in the final clean coal product.
