Basically, Ferrosilicon (FeSi) is a ferroalloy of silicon and iron. The ratio in which the silicon and iron substances are combined differs, with the weight percentage of silicon ranging between 15% and 90%.
Read more here - What is Ferrosilicon
The production process of ferrosilicon 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.
DMS Powders supplies the following Ferrosilicon products:
Coarse, Fine, Cyclone 60, Cyclone 40, DMS 70
65D, 100D, 150D, 270D, 270F
There are a number of uses of Ferrosilicon products, including, but not limited to:
Dense Media Separation is a sink-float method used within the coal, iron ore and especially diamond industries. The powdered ferrosilicon is suspended in water to form a very specific pulp density (heavy liquid), close to the density of diamonds (3.52 g/cm3). The diamond bearing material is then added to the fluid, which will start the separation process of the heavier minerals from the lighter material. Heavier minerals will then sink in the slurry, whilst the lighter materials will rise to the surface.

Our packaging has been specifically designed for:
The production of Ferrosilicon involves the reduction of sand or silica (Si) with coke / coal (C), and then reacting it with iron (Fe) which can be obtained from scraps. This process will usually happen blast furnace or electric arc furnace. The carbon in the coal is necessary to remove the oxygen, leaving a clean Silicon and Iron product as result. The perfect chemical composition needs to be reached to achieve ferrosilicon products with the desired densities and in the right grades.
The usual chemical composition of Ferrosilicon is a Silicon content of 15%, 45%, 75%, or 90%. Most of the remaining compound are made up of iron, with about 2% of other elements, usually aluminium and calcium.
Yes, ferrosilicon is quite toxic, and direct contact should be avoided. When exposed to moisture, ferrosilicon can produce toxic and flammable gasses, hazardous to human health. Ferrosilicon can cause irritation to the skin and eyes, and an irritated respiratory tract when inhaling the gasses. The necessary precautions should be made when handling the product, including personal protective equipment such as filter respirators, goggles, protective gloves and clothes. DMS Powders package ferrosilicon products effectively to ensure safe handling and management without posing a risk, in containers and packaging that are also waterproof.
The ferrosilicon containers supplied by DMS Powders are suitable for storing. First ensure all containers are properly closed when being stored. The ferrosilicon containers should be kept in a dry and well-ventilated area.
A DMS plant, or Dense Media Separation plant, is where diamond recovery / processing takes place. The plant is designed to provide the ideal environment for the process of dense media separation of diamonds, using the law of gravity. Dense Media Separation requires the use of powdered Ferrosilicon, which is combined with water to reach a certain density. The diamond bearing material is added to the mixture, in order for Dense Media Separation to take place. Read more about what a DMS plant is.
Not sure about Milled vs. Atomized Ferrosilicon for your process needs? Milled 15% Ferrosilicon is the most cost-effective option, but quality is however not always constant, leading to difficult operation and inconsistent consumption. Finer grades of Ferrosilicon, leading to higher milling costs, yet causes higher loss. Atomized Ferrosilicon, although more expensive of the two Ferrosilicon ranges, offers lower (and more consistent)consumption. Let the team at DMS Powders assist you to find the correct grade of Ferrosilicon that will meet your application needs. Our team will offer you all the technical assistance you need.
Ferrosilicon is used in a number of different applications and industrial processes, but mainly in diamond processing plants. Ferrosilicon is used to create a medium with a very specific density that will facilitate the separation of diamonds from diamond-bearing material, by means of dense media separation / the sink-float method. Ferrosilicon is manufactured in different grades, each with slightly different characteristics and properties, which makes it easier to select the right grade for use in diamond processing plants. Let a consultant at DMS Powders help you to find the best grade of Ferrosilicon for use in diamond processing plants.

DMS Powders aims to provide the best Ferrosilicon products for use in Dense Media Separation processes, and more specifically, the separation of diamonds from diamond bearing material. Diamond processing plants commonly use Ferrosilicon powders to facilitate the Heavy Medium Separation processes, as it is an effective method when it comes to diamond recovery. Dense Media Separation is a specialised process, and it is essential that the perfect grade of Ferrosilicon with the right physical properties and behavioural characteristics is used, for an effective sink-float process to take place. Read about the characteristics and benefits of Ferrosilicon powders from DMS Powders.
Not sure how ferrosilicon is applied in Dense Media / Heavy Medium Separation? DMS Powders mainly produce Ferrosilicon powder for use in Dense Media Separation of diamonds and minerals. Dense Media Separation involves the mixing of Ferrosilicon powders with water to form a pulp of a certain density, in which the diamond-bearing material is submerged to initiate the sink-float gravity separation process. Dense Media Separation is an effective method when it comes to the initial processing of diamonds.

Diamond mining is a specialised industry and field, requiring highly sophisticated processes. Raw material, namely Kimberlite, is extracted from the diamond mine, and is transported to a diamond plant, for further processing. Diamonds are initially extracted from the Kimberlite (diamond-bearing material) via the process of Dense Media Separation. This method is widely used in diamond plants, due to it being an effective and cost-efficient method to separate diamonds from other material. Ferrosilicon is used in this diamond extraction method, to facilitate the separation process.
