What Is The Raw Material For 45 65 75 Ferro Silicon

The main raw materials used in the production of ferrosilicon are
Silica (SiO2): Silica is usually sourced from silica sand, flint or other forms of silicon dioxide. It serves as the main source of silicon in the ferrosilicon production process.
Iron source: The iron in ferrosilicon is usually sourced from scrap iron or iron ores such as hematite (Fe2O3) or magnetite (Fe3O4). Scrap iron is often preferred due to its availability and cost effectiveness in many cases.
Carbon source: Carbon is used as a reducing agent in the production of ferrosilicon. This can come from materials such as coke, coal or charcoal. The carbon reacts with the silica to facilitate the reduction process, producing silicon and carbon monoxide gas.
Flux (optional): Sometimes fluxes such as lime (CaO) or other materials are added to remove impurities and improve the efficiency of the process.
