Theoretically, the highest iron content in iron ore is around 72%, and iron ore with an iron content above 60% is called rich iron ore. Iron ore is first reduced to iron (pig iron) in a furnace, then sent to a steel-making furnace for decarburization and refined into steel. Scrap steel can also be melted and regenerated in a steel-making furnace.
