Dense Media Separation in Diamond Processing

Dense Media Separation (DMS) in Diamond Processing – DMS Powders

Dense Media Separation is a well-established separation process used in the extraction or processing of diamonds from waste material, and is widely used in the diamond processing and other mineral processing industries.

For this purpose, DMS Powders produces the ferrosilicon powders, which is used in the Dense Media Separation in diamond processing. DMS Powders is a renowned and leading supplier of ferrosilicon powders of the Dense Media Separation of diamonds. Contact DMS Powders today for more information about our ferrosilicon products available.

About Ferrosilicon produced by DMS Powders

DMS Powders is a producer of Ferrosilicon, which is a ferroalloy, a chemical composition of iron and silicon. Ferrosilicon is produced by reduction of silica or sand with coke (fuel) in presence of iron. Ferrosilicon produced by DMS Powders contain 14% - 16% Silicon (by weight) with a Relative Density of 6.8 – 7.1.

DMS Powders supplies a wide range of Ferrosilicon grades for dense media separation (DMS) in diamond processing. Different properties and characteristics of Ferrosilicon includes:

  • Medium Density: The proportion of Ferrosilicon solids present in the medium directly controls the medium density, which can be increased or reduced through adding either Ferrosilicon or water respectively.
  • Medium Viscosity: The medium viscosity is determined by the medium’s resistance to flow (the consistency). The higher the density, the higher the viscosity will be
  • Medium Stability: The medium stability can be described as the tendency of the solids in the medium to settle out. A high stability medium is due to a high concentration of solids, fine particles size in distribution, milled (irregular) shaped particles and the presence of low density contaminating solids.
  • Selection of the Medium: With such a diverse range of Ferrosilicon produced by DMS Powders, it is important to select the correct grade of medium for the specific separation application. The following aspects in should be considered, in density of separation required, size of ore to be treated, sharpness of separation required, and costs.

It has been established that the use of Ferrosilicon is a simple and very effective product for use in dense medium separation (DMS), and specifically in the diamond processing industry - on the condition that the right grade is selected for the specific application.
