Coal Beneficiation - an overview ScienceDirect Topics

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal. Preparation relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

2020-12-10  Although cyclones have been proven capable of processing coal down to fine sizes, it is generally applied only to coal coarser than 0.5 mm in size (de Korte, 2012). One of the disadvantages to the application of DMC on fine coal beneficiation is that there is great loss of magnetite to clean coal products. This technique spans rivalry with spirals which are used for the treatment of fine coal ...
