About DMS Powder’s ferrosilicon products and application

DMS Powder has gained years of experience and knowledge within the production of ferrosilicon powders, for use in the dense media separation of diamonds. This enables us to provide our clients with the best solution for their application needs. We produce atomised and milled ferrosilicon products, available in different grades to fit the requirements of different applications.  

By means of stringent quality control standards, DMS Powders produce a ferrosilicon products with the following attributes:

  • Corrosion resistance: Corrosion ultimately leads to loss of ferrosilicon, and the finer products caused by corrosion can increase the viscosity of the medium. Resistance to corrosion is thus an essential attribute.
  • Abrasion resistance: Our ferrosilicon exhibits strong abrasion resistant qualities, and is produced from high quality material.
  • Magnetic properties: Our ferrosilicon products possess good magnetic properties, allowing easy recovery and de-magnetisation.
  • High specific gravity and economical operating costs are other benefits of our ferrosilicon products, making it ideal for application in Dense Media Separation of diamonds.

Application of ferrosilicon in Dense Media Separation of Diamonds

The process of Dense Media Separation utilises a method of separating valuable material from water-based materials, by means of gravity and density. The dense media separation of diamonds process requires the use of ferrosilicon powders, a Dense Media Separation powder produced by DMS Powders. When the diamond-bearing material is then added to the liquid solution, the separation process to start – The heavier minerals will then separate from the lighter material, for easy diamond recovery.
