FeSi Alloy Ferrosilicon

FeSi Alloy Supplier (Ferrosilicon) – DMS Powders

FeSi (Ferrosilicon) is an alloy of iron, which is produced by melting silicon with quarts, as well as scrap iron, usually in an arc furnace. The most common ratios of Ferrosilicon are 50%, 65% and 75%. DMS Powders is a leading supplier of FeSi alloy, Ferrosilicon, for use in the process of Dense Media Separation.

Ferrosilicon from DMS Powders – FeSi for use in Diamond processing plants

Dense media separation is the separation process of diamonds from diamond bearing material. The diamond bearing material is submerged in a liquid / pulp with a very specific density, which is where FeSi alloy, Ferrosilicon, comes in. The dense pulp is achieved by mixing the Ferrosilicon powder with water, until the desired density is reached. This liquid will cause the diamonds to separate from other material, making the processing of diamonds easier.

DMS Powders supplies a wide range of Atomised and Milled ferrosilicon grades, to fit the needs of different applications and requirements. Density, Viscosity and Medium are essential properties to consider when selecting a ferrosilicon grade for the specific application in dense media separation. Once the operating density has been determined, the correct viscosity and stability needs to be calculated.

Range of Milled and Atomised Ferrosilicon (FeSi) products from DMS Powders

DMS Powders produces and supplies Milled and Atomised Ferrosilicon products:

  • Milled Ferrosilicon products: Milled Ferrosilicon products from DMS Powders include 65D, 100D, 150D, 270D, 270F. The production of Milled Ferrosilicon requires melting steel in an induction furnace, after which the molten FeSi alloy is then tapped onto a sand bed until it has cooled. The product is then crushed and milled into the desired particle sizes.
  • Atomized Ferrosilicon products: Atomized Ferrosilicon products from DMS Powders include Coarse, Fine, Cyclone 60, Cyclone 40 and DMS 70. Atomized Ferrosilicon is produced by melting Ferrosilicon with high grade steel in an induction furnace. The fine particles produced are then separated via screens, and classified according to grade. DMS Powders’ Atomized Ferrosilicon products include Coarse, Fine, Cyclone 60, Cyclone 40 and DMS 70.
