    Generation of iron and steel slag NIPPON SLAG

    While limestone may seem unrelated to the production of iron and steel, it actually is an essential auxiliary material that is added during the production process. During the process of reducing iron ore, it is necessary to remove the silica, alumina Al 2 O 3, and other non-ferrous components contained in iron ore. The added limestone fuses with these components and lowers their melting point, making it
