Coal Beneficiation an overview ScienceDirect Topics
Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

Jul 18, 2018 The first step of Beneficiation is to crush or grind the coal to liberate the coaly matter from ashy matter which can theoretically yield complete liberation. In the case of intergrown texture, finer grinding up to a few micron size is necessary for complete liberation whereas for free dirt ordinary crushing is sufficient (Kumar, D., 1982).
