In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which is produced from iron ore by means of direct reduction (= DRI or directly reduced iron) and that is then further reduced and smelted in an electric furnace.
