Pre-sized raw coal (-50 x 0 mm) is mixed with water and passed over a deslime screen to remove the fine material i.e. below 0.5 mm or 1.0 mm in size. The undersize material passes to the fines treatment circuit(s) and the oversize 'deslimed coal' is mixed with the correct medium and pumped to a dense medium cyclone by the cyclone feed sump.
