Currently, the most efficient coal beneficiation method is "float-and-sink separation" which increases productivity and separation. By using cyclones with accurate cut-point control, different densities of coal can be separated. DMS makes use of magnetite as a separation medium to improve the accuracy of cut-point separation.
