What is Dense Media Separation?
During the process called Dense Media Separation (DMS), particles are largely separated according to their densities using gravity. A medium suspension of a given density is filled with particles with a variety of densities. Lighter than the medium density particles rise. These are referred to as ‘floats’. ‘Sinks’ are generally used to describe particles that are heavier than the mean density, causing them to sink to the bottom or sides of the tank. Dense Media Separation is therefore also commonly known as the sink-float method, or Gravity Separation Process.

The use of Ferrosilicon in Dense Media Separation
Ferrosilicon is a powder-like substance that is used in the Dense Media Separation process. It is used to make the suspension in which the particles are submerged, by mixing it with water. Ferrosilicon possesses the ideal physical properties to achieve the optimal level of Stability, Viscosity and Density of the medium, to facilitate effective separation of the particles. Ferrosilicon is manufactured in various Grades, that differ in physical characteristics, in order to achieve different properties in suspensions.
DMS Powders – Producer of Ferrosilicon for Dense Media Separation
DMS Powders is a leading manufacturer and supplier of Ferrosilicon, producing an extensive range of quality Ferrosilicon powders for use in the Dense Media Separation of Diamonds. In diamond processing, Dense Media Separation is used to separate diamonds and other minerals from diamond-bearing material e.g. Kimberlite. The Kimberlite is submerged in the mixture, and will cause the heavier particles (diamonds) to separate from the lighter materials.
This process is widely used in diamond plants across the world due to its effectiveness, cost-efficiency and ease of use. Ferrosilicon from DMS Powders is ideal for Dense Media Separation, and offers the following advantages:
- Narrow particle size distribution results in predictable medium behaviour.
- Excellent recovery due to the medium’s high magnetic susceptibility.
- High medium specific gravity.
- Low operating expenses because of the medium’s high specific gravity and magnetic recoverability.
DMS Powders manufacture the following Ferrosilicon products for Dense Media Separation:
- Atomised FeSi – Coarse, Fine, Cyclone 60, Cyclone 40, DMS 70.
- Milled FeSi – 65D, 100D, 150D, 270D, 270F.
