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.
