The process of Dense Media Separation requires the suspension of Ferrosilicon powders in water, which will form a thick fluid near the density of diamonds, which is 3.52 g/cm3. The material bearing the diamonds are then added to the pulp after which the diamond separation starts. The higher density medium will thus separate from lower density material, in order to separate the diamonds from the diamond-bearing material. This is an effective method used in DMS plants across the world, offering a reliable diamond recovery method.

DMS powders produces and supplies Ferrosilicon products for the purpose of Dense Media Separation of Diamonds. We supply two types of Ferrosilicon, namely:

• Atomized Ferrosilicon: The process of manufacturing Atomized Ferrosilicon requires 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.
• Milled Ferrosilicon: The method to produce Milled Ferrosilicon requires melting steel in an induction furnace, after which the molten alloy is then tapped onto a sand bed until cooled. The ally is then crushed and milled into the desired particle sizes.

DMS Powders is a leading producer of Ferrosilicon powders used in DMS plants, offering clients reliable and effective products at very competitive prices. Our Milled and Atomized Ferrosilicon products are also conveniently packed to ensure easily handling, safe transportation, durable packaging and resistance to water.
