Description: DR Congo Customer 200TPH diamond Processing plant, including feeding system, sand washing machine, crush machine, sieving and DMS system

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 separation of the denser material occurs by centrifuge in “cyclones” that swirl the mixture at low and high speeds, forcing the diamonds and other dense minerals to the walls and then out the bottom of the cyclone. Wastewater rises at the center of the cyclones and is sucked out and screened to remove waste particles.  The DMS process results in a concentrate that generally weighs less than one percent of the original material fed into the plant at the beginning of the process.
Dense Media Separation Advantages
1. Lower basic investment and operating costs
2. Can deal with low-grade resources and improve ore production
3. Environment-friendly operation
Although heavy media separation has been recognized since the last century and used in coal washing, in mineral processing, hydrometallurgy or pyrometallurgy processes, as a general process, heavy medium separation is not really shown before fine grinding of ore. It is proved that the method of heavy medium separation can effectively separate diamond and other precious stones and treat copper, lead and zinc ores. In some cases, effective recovery of gold and PGM, the improved method can also be an effective separation of non-metallic minerals, like barite, fluorite and other industrial minerals. In the non-mine field, heavy medium separation technology can be used to treat waste vehicle debris, renewable resources, industrial and municipal waste and electronic waste. More details of DMS plant
