Limestone is a primary ingredient used in the production of iron by the blast furnace process. It is used to remove impurities like silica and alumina from the iron ore, and also to help form slag, which is an important byproduct of the process. Bromide, sulfate, and sulfide are not used in the blast furnace process.
