What is ferrosilicon used for?

Ferrosilicon is an alloy of iron and silicon.Ferrosilicon is coke, steel chips, quartz (or silica) as raw materials, smelted by electric furnace made of iron silicon alloy.Common uses of ferrosilicon are as follows:

View Details

(1) ferrosilicon is an essential deoxidizer in steelmaking industry.In steelmaking, ferrosilicate is used for precipitation deoxidation and diffusion deoxidation.Brick iron is also used as an alloying agent in steelmaking.

(2) Used as inoculant and spheroidizer in cast iron industry.In the production of ductile iron, ferrosilicon is an important inoculant (to help precipitate graphite) and spheroidizer.

(3) used as reducing agent in ferroalloy production.Not only is the chemical affinity between silicon and oxygen great, but the carbon content of high silicon ferrosilicon is very low.Therefore, high silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low carbon ferroalloy in the ferroalloy industry.

(4)75 ferrosilicate in Pijiang magnesium smelting is often used in the high temperature smelting process of magnesium, the magnesium replacement in CaO.MgO, each one ton of magnesium will consume about 1.2 tons of ferrosilicate, which plays a great role in the production of magnesium.

Application of Ferrosilicon from DMS Powders

Ferrosilicon manufactured by DMS Powders can be used in a number of applications, but the main use being in Dense Media Separation processes. Dense Media Separation, or the sink-float method, is an effective process used to separate diamonds from diamond bearing material. This process to initially sift diamonds is used in diamond plants across the world, due to its effectiveness and because it is cost effective as well.

The Ferrosilicon is used by mixing it with water in a cyclone, to form a pulp of a very specific density (close to the density of diamonds). The cyclone will help to push material with heavier density to the bottom and sides, while material with lower density will float, thus separating diamonds (or iron and other minerals) from material effectively.

DMS Powders manufacture a comprehensive range of quality Ferrosilicon powder for use in Dense Media Separation, offering Ferrosilicon in different grades with different specifications. This will help you to get the best Ferrosilicon product for your specific diamond processing needs. You can read more about the technical information and behavioural characteristic of our Ferrosilicon products, or get in touch with a professional consultant at DMS Powders today for the information you require.
