Get the best Ferrosilicon for the Dense Media Separation of Diamonds & Minerals. Partner with DMS Powders.
When it comes to separating valuable minerals from waste rock, few materials are as effective as ferrosilicon. Dense Media Separation (DMS) plants across the globe rely on this alloy to keep operations consistent and profitable. If you’re looking to buy ferrosilicon for dense media separation, it’s worth understanding not only the product itself but also the expertise behind the manufacturer you choose.
At DMS Powders, we’ve been producing atomised and milled ferrosilicon for decades, helping mines and mineral processors achieve reliable performance, cost efficiency, and precise separation results.
Technology:
Why Ferrosilicon is Essential in DMS Plants
Ferrosilicon is more than just a raw material; it’s the backbone of dense media separation. The process involves creating a suspension of ferrosilicon powder in water to form a liquid of higher density than water alone. When ore passes through this “heavy liquid,” denser particles sink while lighter material floats, allowing operators to recover diamonds, base metals, and other minerals with high accuracy.
In diamond processing, ferrosilicon is particularly important. The ability to consistently separate heavy stones from lighter host rock determines yield, recovery rates, and ultimately profitability. DMS Powders works closely with clients who demand precision in this environment, producing products that deliver consistent results across varying ore bodies and plant conditions.
If you’d like to learn more about how ferrosilicon works in diamond recovery plants, you can read our section on dense media separations of diamonds.
Ferrosilicon Grades and What They Mean for You
Not all ferrosilicon products are the same. The grade you select—whether atomised or milled—determines efficiency, recovery, and cost-effectiveness.
Atomised Ferrosilicon
Atomised grades such as Coarse, Fine, Cyclone 60, Cyclone 40, and DMS 70 are produced using a highly controlled atomisation process. This ensures spherical particles with excellent flow and recovery characteristics. Atomised ferrosilicon is often preferred in plants where stability and quick recovery are vital.
Milled Ferrosilicon
Milled ferrosilicon is produced by grinding down atomised particles to create angular powders. Grades such as Ferrosilicon 65D, 100D, and 150D are common choices in DMS plants. Each grade offers a balance between density, magnetic properties, and operating costs:
- Ferrosilicon 65D – durable and reliable, often used in plants needing steady recovery under demanding conditions.
- Ferrosilicon 100D – versatile and suited for a range of mineral separation environments.
- Ferrosilicon 150D – fine particles designed for tighter control, delivering high accuracy in complex ore bodies.
Clients who need consistency across large-scale operations often select these grades because they reduce variability and help keep costs predictable. You can find out more about our ferrosilicon atomised and milled products for specific applications.
