Therefore, DMS methods are widely used in the separation of coal and various metal ores and nonmetallic ores. Direct separate clean coal and waste rock; separate coarse waste tailings and rough concentrate. For the ordinary gravity separation method, the lower limit of the feeding ore is about 23mm (the coal is 36mm).
