In nature, elemental iron is found largely in either magnetite or hematite, both iron ore minerals. Nearly all iron ore — whether used directly as lump ore or converted to briquettes, concentrates, pellets or sinter — is used to make steel. In the United States, steelmaking accounts for almost 99 percent of iron ore consumption.
