Ferrosilicon Production

Ferrosilicon products from DMS Powders

Ferrosilicon is a ferroalloy, comprising of iron and silicon, with 15 – 95% silicon. Ferrosilicon is used for the Dense Media Separation of Diamonds, as well as other applications such as a basis for the manufacturing of pre-alloys such as Magnesium Ferrosilicon (FeSiMg).

DMS Powders is a leading ferrosilicon producer, supplying milled and atomised ferrosilicon to client. Contact DMS Powders today about our ferrosilicon grades available for your process needs. We will advise you on the best ferrosilicon to fit your requirements. Read more about the ferrosilicon production and application, as well as types and grades of ferrosilicon.

Ferrosilicon production and application

The production process of ferrosilicon basically entails the reduction of silica, sand and coke, whilst in the presence or iron. Depending on the silicon content, this process will either take place within a blast furnace or electric arc furnace. There are two types of ferrosilicon that exits, as produced by DMS Powders, namely milled ferrosilicon and atomised ferrosilicon (defined in terms of their production process). Atomised ferrosilicon possesses a more spherical shape, where milled ferrosilicon is more angularly shaped.

Atomised ferrosilicon is generally used in the Dense Media Separation applications, and can be produced in different grades. These types are directly related to size distribution, namely Coarse, Fine, Cyclone 60, Cyclone 40 and DMS 70, used in applications where the separating density is greater 3.0sg (specific gravity).

Milled ferrosilicon is widely used in applications where the separation medium is lower than 3.2sg. Again, a range of milled ferrosilicon is produced directly related to the size distribution, namely 65D, 100D, 150D, 270D and 270F.

At DMS Powders, we produce a wide range of ferrosilicon grades, to fit various application needs. The specific application will determine which ferrosilicon grade will be required, as the in-circuit behaviour of the ferrosilicon is determined by the physical property of the specific ferrosilicon. Density, Viscosity and Medium are very important properties to consider in the selection of the ferrosilicon grade for application.
