DMS Powders:
What is Milled Ferrosilicon? Uses and specifications
Milled Ferrosilicon is a granular or powdered form of Ferrosilicon, specifically designed for use in the separation media of DMS circuits. It is produced by crushing oversized particles left over from the production of atomised Ferrosilicon, creating an angular, high-density powder ideal for gravity separation processes. The combination of angular shape and high iron content improves media stability and sink-float accuracy, especially in dense medium cyclones.
The Ferrosilicon manufacturing process begins with melting steel scrap and silicon in induction furnaces to produce a 75% silicon alloy. This molten material is atomised into particles using high-pressure steam, and once cooled, oversized particles are milled to specific mesh sizes to form the milled Ferrosilicon range.
At DMS Powders, our milled Ferrosilicon products are available in various grades including:
- 65D
- 100D
- 150D
- 270D
- 270F
Each grade is carefully lab-tested for consistency, ensuring controlled particle size distribution, slurry stability, and superior magnetic recovery during processing.

Applications of Milled Ferrosilicon in Dense Media Separation
Dense Media Separation (also known as heavy media separation) is an industrial process widely used across mining operations and metallurgical plants for the classification and separation of materials based on density. The DMS process involves mixing milled Ferrosilicon with water to create a slurry with a precisely controlled Ferrosilicon density.
This mixture is then used in a dense medium cyclone, where it facilitates the separation of minerals such as:
- Diamonds
- Manganese
- Chromite
- Base metal ores
- Industrial minerals
- Iron ore
Heavier, valuable particles sink, while lighter waste particles float, enabling an efficient and cost-effective separation medium. This method is particularly effective in diamond recovery plants, coal washing facilities, and mineral processing plants due to the robustness and recyclability of Ferrosilicon in DMS systems.

Frequently Asked Questions About Milled Ferrosilicon
What’s the difference between atomised and milled Ferrosilicon?
Atomised Ferrosilicon has a more spherical shape and is primarily used when higher density and flow are required. Milled Ferrosilicon, being angular, provides enhanced media stability and magnetic recovery, making it ideal for specific DMS applications.
How do I choose the right Ferrosilicon grade?
The right grade depends on your DMS circuit design, particle size, required slurry density, and the mineral type being processed. Speak to our specialists for custom recommendations.
What packaging options are available for bulk orders?
We supply Ferrosilicon in bulk bags, steel drums, and custom packaging solutions to fit your facility’s logistics and storage requirements.
