Diamond Extraction & Processing – DMS Powders
Although there are various methods used world-wide for the recovery and extraction of diamonds, one of the main methods used is a process called Dense Media Separation. Dense Media separation is a process that requires the use of Ferrosilicon, an alloy of iron and silicon, to facilitate the separation process.
DMS Powders produces a range of Ferrosilicon powders, for use in Dense Media Separation processes. It is essential that the right grade of Ferrosilicon powder is used in order to facilitate effective separation of diamonds and minerals from diamond-bearing material. The characteristic of different Ferrosilicon grades differ in terms of Density, Viscosity and Stability, which are all interrelated. DMS Powders will supply you with the best Ferrosilicon grade for your Dense Media Separation process, to ensure satisfying results.
Atomised FeSi: Coarse, Fine, Cyclone 60, Cyclone 40, DMS 70
Milled FeSi: 65D, 100D, 150D, 270D, 270F

The dense media separation process for diamond extraction
Dense Media Separation, also called the ‘sink-float’ method, requires the use of Ferrosilicon powders.
The Ferrosilicon is mixed with water to form a fine suspension until it reaches the desired density (close to the density of diamonds). The diamond or mineral bearing material is the submerged into the pulp mixture (in a cylindrical tank), in order for dense media separation to take place. Particles that are denser than the medium will report to the process underflow as sinks, while less dense particles will report to the process overflow as floats. Dense Media Separation is widely used as a diamond extraction method, due to the effectiveness of the process, and because it is cost-efficient.
