Mineral Resource of the Month Iron OreEARTH Magazine

   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.

2 Iron ore production. The EU has 9 member states producing iron ore including Sweden Norway Austria Slovakia and Germany. However Sweden and Norway are the only countries in which significant quantities of iron ore are mined (Fig. 1). The quantities of iron produced from the mined ore have been between 19.1 Mta and 21.8 Mta in recent years.
