Heavy Media Gravity Separation

Heavy Media Gravity Separation – DMS Powders

Heavy media gravity separation is a process that involves the separation of different materials according to density. A mixture of fine media and water is combined to form a slurry that possesses a very specific gravity / density. This mixture will allow low density media to rise above the medium, and high density material to sink below the medium. Ferrosilicon is widely used in the application of heavy media gravity separation, due to its specific properties and density.

DMS Powders is a leading producer of Ferrosilicon for heavy media separation processes in the diamond recovery industry. If you need a supplier that offers competitive prices and high quality Ferrosilicon products, contact DMS Powders today for more information.

Grades of Ferrosilicon for Heavy Media Separation

Choosing the right grade of Ferrosilicon is essential for efficient dense media separation of diamonds and other minerals. The following properties should be taken into account when selecting Ferrosilicon powder for heavy media gravity separation:

  • Medium Density: The density of the medium will determine at which density the separation will take place. This variable will assist the controller to manage the heavy media separation process.
  • Medium Viscosity: The viscosity of the medium will determine to what extent the medium is resistant to flow.
  • Medium Stability: The medium stability refers to the tendency of the solids in the medium to settle out and is directly related to the medium viscosity.
