Dense Medium Separation | Industries | Chemical Engineering

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.


The density of the ferrochrome slag is between 2.5- 2.8 g/cm 3 and that of ferrochrome 6.8 g/cm 3. The viscos-ity of slag is a function of the pressure and temperature. The viscosity also has an essential meaning in the separation of slag and metal. The viscosity of the fe rrochrome slag will increase when the content of SiO 2 and

Suppliers & Manufactures of Atomised Ferro Silicon 15%

Atomised Ferro Silicon 15% is mixed in water to create a dense medium and finds uses in the mining and scrap processing industries. Dense medium separation is a gravity separation technique which creates a medium with a specific density. This medium allows lights to float and heavies to sink, thus permitting separation due to density.
