Heating. Air that has been heated to around 1,°C is injected into the furnace, converting the iron ore to molten pig iron and slag. Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they. About 95% of this iron is processed further to make steel, often by the open-hearth process or the Bessemer process, but more recently in the United States and.
