The use of Ferrosilicon in Dense Media Separation

Dense Media Separation is a process widely used in the diamond and mineral processing industry, to separate diamonds from diamond-bearing material. This process is effective and cost-efficient, and required the use of Ferrosilicon powders.
To facilitate the Dense Media Separation process, Ferrosilicon is mixed with water in a cyclone to form a pulp of a very specific density. The diamond-bearing material is submerged into the pulp, so that the separation process can begin. Denser or heavier material will sink to the bottom or be pushed out the sides of the cyclonic action, while lighter material will float. For this reason, dense media separation is also referred to as the sink-float method. This separation method has proven to be very effective, which is why it is commonly used across the globe to separate diamonds, minerals, ore bodies and scrap metal from the material it is present in.

Technical aspects and characteristics of Ferrosilicon

Before purchasing just any Ferrosilicon products for sale for your sink-float process, it is essential that you select the right type and grade of Ferrosilicon for the best results.

The physical properties of the Ferrosilicon particles will determine the properties of the medium (mixture of Ferrosilicon and water), with regards to medium density, stability and viscosity, which are interrelated. In order to meet the needs and requirements of various processes, DMS Powders manufacture different Ferrosilicon for sale to choose from, namely:

  • Atomised Ferrosilicon: Atomised Ferrosilicon feature more spherically shaped particles, and is available in Coarse, Fine, Cyclone 60, Cyclone 40 and DMS 70.
  • Milled Ferrosilicon: Milled Ferrosilicon feature more angularly shaped particles, and is available in 65D, 100D, 150D, 270D and 270F.

Let the team from DMS Powders help you to select the best type and grade of Ferrosilicon for your process requirements.
