Ferrosilicon for Dense Media Separation
The Dense Medial Separation process requires the use of Ferrosilicon, mixed with a liquid, to form a mixture of a density close to that of diamonds. This is mixed in a cyclone or tank, in which the Dense Media Separation will take place. The diamond-bearing material is added t the mixture, and the circular movement of the mixture will allow ...

Ferrosilicon Producers – Dense Media Separation
Dense media separation is one of the two methods used for diamond recovery that makes use of powdered ferrosilicon. The powdered ferrosilicon is suspended in water, forming a liquid near the density of the diamonds. The diamond-bearing material is then added to the liquid in order for the separation process to start.

What is a DMS Plant?
A DMS plant, or Dense Media Separation Plant, involves a process that uses the principle of gravity to separate materials with different densities. Dense Media Separation is an efficient initial process to separate diamonds from diamond bearing material, after which the material will be further processes for the final diamond recovery.

The art and science of dense medium selection
Dense medium separation (DMS) is a process whereby particles are sorted primarily on the basis of their densities. Particles with a wide range of densities are introduced into a medium suspension of a given density. Particles that are lighter than the medium density rise. These are commonly referred to as floats.

Dense Media Separation
After separation, the dense medium is recovered using screens and magnetic separators, and then it is cleaned and reused. DMS is a powerful and efficient technique due to its high capacity, ability to treat a wide range of particle sizes (from 75 mm down to less than 0.5 mm), and high efficiency in separating different minerals based on density.
