Dense Media Separation (DMS) Plants

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 (3.52 g/cm3), to which the diamond-bearing material is added to begin the separation process of the heavier minerals from the lighter material. Additional ...

How it works

To obtain a heavy media with the specific gravity most suitable for the separation, it is necessary to increase or decrease the concentration of Ferrosilicon or Magnetite dispersed in water. In industrial plants, the heavy media is pumped and kept in circulation inside a Rotating Drum Separator where the 'bath' is created in which the ...

Heavy-media Cyclones for coal cleaning

Like the heavy-media vessels, Heavy-media Cyclones also are designed to clean coal and minerals based on their density differences. Using finely ground magnetite and water as the media to create a buoyancy effect for gravimetric separation, the Heavy-media Cyclone forces the lighter solids to its centre, where the slurry transports them upward and …
