Therefore, DMS methods are widely used in the separation of coal and various metal ores and non-metallic 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 2-3mm (the coal is 3-6mm).

Coal separation technologies. Several different technologies take advantage of the density difference between coal and unwanted rock and mineral fragments mixed with or attached to the coal. Coal has relatively low density or specific gravity (1.2 to 1.5) compared to other rocks such as shale (2.4 to 2.8) or minerals such …

It has a raw capacity between 500 and 1,000 tons per hour. Although more plants are employing large diameter cyclones, the plants still rely mainly on heavy-media vessels for primary separation and heavy media cyclones for intermediate separation. For fine coal recovery, the plants prefer spirals. Centrifugal dryers are popular.
