Leeuwpan fine coal dense medium plant J r n a. The dense media separation (DMS) plant at Leeuwpan was commissioned in 1997. The plant originally treated three Witbank coal seams, namely seams no. 2, 4 and 5. A coal jig plant was built in 2005 to treat the top layer of coalSeams 4 and 5to supply a 30% ash coal to power stations.
Dense medium separation can be performed using a variety of mediums. These include, organic liquids, aqueous solutions or suspensions of very fine particles in water or air. The organic liquids are typically not used due to their toxicity, difficulties in handling and relative cost.
A coal dense medium separation (DMS) plant makes use of the principle of density separation to upgrade mined coal and produce metallurgical coal or power station coal. The objective of the DMS plant operation is to produce coal product within a minimum quality specication and maximum possible yield (England et al., 2002).
For example, a 400 tph feed to a dense medium process equates to a volumetric flow rate of 1000 gallons/min or m 3 /min. At a 4:1 mediumtocoal ratio, the volume of medium is m 3 /min. To achieve a #207; m = RD, the required amount of magnetite in the medium is 704 kg per m 3 of medium or 10664 kg/min = tonnes/min. Magnetite

In a Dense Media Separation (DMS)/ Heavy Media Separation( HMS) plant, powdered ferrosilicon (an alloy of iron and silicone) is suspended in water to form a fluid near the density of diamond ( g/cm3), to which the diamondbearing material is added to begin the separation process of the heavier minerals from the lighter material.
DENSE MEDIA SEPARATION (DMS) PLANTS The DMS process is employed for the preconcentration of suitable ores upstream from expensive downstream metallurgical processes, and also employs the separation of heavy waste particles (such as metals) from light waste particles.
