DENSE. MEDIUM SEPARATION. DENSE MEDIUM SEPARATION (DMS) It is a physical separation technology which relies on the difference in material densities to separate different materials. The mixed solids are placed in a liquid denser than one and less dense than others. The denser material sinks while the less dense material floats.

Dense Medium Separation - An Effective and Robust Pre ...

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.
