What is a DMS Plant?

Diamond processing / diamond recovery involves the separation of diamonds and other minerals from diamond bearing material. There are different methods when it comes to diamond recovery, one of which requires the use of 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.

  • Atomised FeSi

    Coarse, Fine, Cyclone 60, Cyclone 40, DMS 70

  • Milled FeSi

    65D, 100D, 150D, 270D, 270F

How does a Dense Media Separation plant work?

A DMS plant requires the use of Ferrosilicon, a Ferroalloy of Silicon and Iron, which is used in a powdered form. The Ferrosilicon powder is suspended in water, to form a pulp that is close to the density of diamonds (3.52 g/cm3). Once the ideal density is reached, the diamond bearing material is added to the slurry, and the separation process will begin. Gravity will make the heavy minerals sink to the bottom, while the lighter material will rise to the top. This process effectively separates diamonds from other material using the law of gravity. The mixture will also swirl at low speed, which will force heavier materials to the walls and bottom of the cyclone, to be filtered from the rest.

DMS Powders - Supplier of Ferrosilicon for DMS plants

DMS Powders is a leading producer of Ferrosilicon for use in the process of Dense Media Separation of diamonds. DMS Powders producer two different Ferrosilicon products, namely:

  • Milled Ferrosilicon: Milled Ferrosilicon is angularly shaped, and available in: 65D, 100D, 150D, 270D, 270F products. The production of Milled Ferrosilicon requires melting steel in an induction furnace, after which the molten alloy is then tapped onto a sand bed to cool off. Once cooled, the alloy is then crushed and milled into the desired particle sizes.
  • Atomized Ferrosilicon: Atomized Ferrosilicon is spherical shaped, and available in Coarse, Fine, Cyclone 60, Cyclone 40, DMS 70. The process of manufacturing Atomized Ferrosilicon requires melting Ferrosilicon with high grade steel in an induction furnace, which is then cast into a high-pressure water jet. The fine particles produced are then separated via screens, and classified according to grade.
