Extracting Iron from Iron Ore in a Blast Furnace Essay ...

Many things are produced in the extracting or iron from iron ore in a blast furnace. The iron ore is reacted with carbon and oxygen in the furnace to produce carbon dioxide and iron metal. Carbon monoxide is also produced so that it can react with the iron ore to produce the iron. At the end, there is left the molten iron and the slag.

Iron processing |

Two byproducts, slag and gas, are also formed. Slag leaves the furnace by the same taphole as the iron (upon which it floats), and its composition generally lies in the range of 30–40 percent silica (SiO2), 5–15 percent alumina (Al2O3), 35–45 percent lime (CaO), and 5–15 percent magnesia (MgO).
