on top of that, the steelmaking process requires breaking the chemical bond in iron ore to get access to pure iron, a reaction that requires a reagent to bind with oxygen. broadly speaking, in the last 2,000 years of steelmaking, that reagent has been coal, which generates co 2 as a by-product.1 1 iron ore comes in two forms, either hematite (fe 2 o 3) or magnetite (fe 3 4), which both produce pig iron (fe) and.beneficiation of iron ores – ispatguru,beneficiation of iron ores. iron ore is a mineral which is used after extraction and processing for the production of iron and steel. the main ores of iron usually contain fe2o3 (70 % iron, hematite) or fe3o4 (72 % iron. magnetite). ores are normally associated with unwanted gangue material..chemical composition analysis of raw materials used …,the iron ore sintering process is the largest source of emissions of dust and gas pollution in the iron and steel industry. hematite ores, magnetite concentrates, admixtures (dolomite, limestone and burnt lime), fuels (coke breeze, anthracite) and by-products are used in poland to produce the sinter mixture. key words: iron ore sintering process; chemical composition; raw materials, poland introduction the iron ore.cost effectiveness analysis of hyl and midrex dri,arc furnace (eaf). the bf-bof is a two-step process. first, in the blast furnace, mined iron ore is combined with limestone and coke to form molten iron. the purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called “hot metal” (blast furnace, 2016). integrated steel
