  • 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 alloy of iron and silicon 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: Atomised Ferrosilicon products from our Ferrosilicon company include Coarse, Fine, Cyclone 60, Cyclone 40 and DMS 70. Atomised 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’ Atomised Ferrosilicon products include Coarse, Fine, Cyclone 60, Cyclone 40 and DMS 70.

Industrial Uses of Ferrosilicon

Ferrosilicon (FeSi) is an essential alloy with a broad range of industrial applications, thanks to its unique properties that make it invaluable in various processes. Its primary uses span the steelmaking, foundry, and metallurgical industries, where it serves as a crucial component in enhancing product quality and efficiency. DMS Powders specialises in providing ferrosilicon for Dense Media Separation (DMS) processes in diamond and mineral processing, but the utility of FeSi extends far beyond these applications.

Here are the main uses of Ferrosilicon:

  1. Steelmaking

One of the most significant uses of ferrosilicon is in the production of steel. In steelmaking, FeSi is used as a deoxidiser and an alloying agent. During the steelmaking process, oxygen must be removed to prevent oxidation, which can weaken the final product. Ferrosilicon is introduced to the molten steel, where it reacts with oxygen to form silica, which can then be easily removed. Additionally, FeSi adds silicon to the steel, enhancing its strength, flexibility, and resistance to wear and corrosion.

  1. Foundry Industry

In the foundry industry, ferrosilicon plays a critical role in the production of cast iron. It is used as an inoculant to improve the properties of cast iron by controlling the solidification process. This results in a more uniform and predictable microstructure, leading to cast iron products with better machinability, strength, and durability. Ferrosilicon is also employed to produce various types of cast iron, including ductile iron, which is widely used in automotive and heavy machinery applications.

  1. Magnesium Production

Ferrosilicon is an essential component in the production of magnesium, a lightweight metal used in the automotive, aerospace, and electronics industries. The Pidgeon process, the most common method of magnesium production, involves reducing magnesium oxide with ferrosilicon. The high silicon content in FeSi acts as a reducing agent, facilitating the extraction of pure magnesium from its ore.

  1. Welding Electrode Coatings

Ferrosilicon is also used in the manufacturing of welding electrodes, particularly in coatings. The presence of silicon helps to stabilise the arc during welding and improves the quality of the weld by reducing impurities and enhancing the flow of molten metal. This results in stronger, more reliable welds in various industrial applications.

  1. Other Metallurgical Applications

In addition to the above uses, ferrosilicon is utilised in various other metallurgical processes. It is a critical ingredient in the production of silicon steel, which is used in electrical transformers and motors due to its excellent magnetic properties. Ferrosilicon is also used in the production of silicon alloys and as a reducing agent in the production of other metals, such as chromium and manganese.

  1. Dense Media Separation in Diamond and Mineral Processing

At DMS Powders, our focus is on providing top-quality ferrosilicon products for Dense Media Separation (DMS) processes in the diamond and mineral processing industries. In these applications, FeSi is used to create a dense medium that facilitates the separation of valuable minerals from waste material based on density differences. Our ferrosilicon products are specifically engineered to offer the stability, consistency, and efficiency required for effective separation in these critical industries.

By supplying FeSi tailored for DMS processes, DMS Powders supports the mining sector in achieving optimal yield and quality in diamond and mineral extraction. Whether used in steelmaking, foundries, or DMS processes, ferrosilicon is a versatile and indispensable material across numerous industries.
