Production of Ferro-Silicon. Ferro-silicon (Fe-Si) is a ferro-alloy having iron (Fe) and silicon (Si) as its main elements. The ferro-alloy normally contains Si in the range of 15 % to 90 %. The usual Si contents in the Fe-Si available in the market are 15 %, 45 %, 65 %, 75 %, and 90 %. The remainder is Fe, with around 2 % of other elements

Silica fume is a by-product of the manufacture of silicon and ferrosilicon alloys from high-purity quartz and coal in a submerged-arc electric furnace. The SiO2 content is generally in the range between 80 and 98 mass%. The process produces a very fine material, which has a high pozzolanic reactivity.

Production Process of Ferrosilicon: DMS Powders produce both Milled and Atomised Ferrosilicon. The process of Ferrosilicon production 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. The Carbon in the coal is required to remove the oxygen, leaving a pure Silicon and Iron (FeSi) product. Read more about the

Production processes. Ferro-alloys are usually produced by the reduction of a metallic ore (generally oxide) by carbon with the addition of electric energy in a "Submerged Arc Furnace" (smelting process); or by metals (metallo-thermic reduction), usually aluminium or silicon. High carbon ferro-manganese is produced by the reduction of manganese
