If it contains more than 2% carbon, it’s known as a different product called pig iron. melting down iron ore with coke to create pig iron is an easy way of processing it, and is often an intermediate step in the refining process. pig iron then gets processed to reduce the amount of carbon in it, turning it into.
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.
