The iron obtained from blast furnace
Web12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the WebThe process of extraction of iron is blast furnace. The slag that is obtained on the iron ore is separated and cooled down slowly, which results in the formation of nonreactive crystalline material. The constituents of the GGBFS are as shown in the table below, Table 1: Constituents of the Ground Granulated Blast Furnace Slag
