From ore to steel – ArcelorMittal

The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon.

Extraction of Iron | Metallurgy | Blast Furnace and Reactions

This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast ...

Iron Production - chem.libretexts.org

The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides.

Iron Smelting | Essential Humanities

Rock that is rich in a valuable mineral is referred to as ore. Most iron ore contains some form of iron oxide (e.g. Fe 2 O 3, Fe 3 O 4). 3 In order to extract iron from iron ore, one must first remove the unwanted minerals, then remove the oxygen from the iron. The latter step can only be achieved with a chemical reaction.
