Lime is used to convert iron into 'pig iron'. In the blast furnace, finely ground or granular limestone (with a low sulfur and alkali content) is used together with finely ground lime to convert ore into pig iron. The pig iron is later processed into steel. Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces.
