Iron ore is used for the production of metallic iron in steel-making. Although some 45 countries export natural iron ore resources, seven countries provide 75% of the total exported. The two largest exporters are Brazil and Australia, with about 33% of total world exports each. Other exporting countries include Chile, India, South Africa, Canada, Russia and the United States.


iron. resources are mainly low-grade taconite-type ores from the Lake Superior district that require beneficiation and agglomeration prior to commercial use. World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. Substitutes: The only source of primary iron is iron ore, used directly as direct-shipping ore or

Algoma-, Superior-, and oolitic-type iron deposits of the

High-grade hematitic iron ores (or HIF, containing 60–65 percent Fe) have been mined in Mauritania from Superior-type iron deposits since 1952. Depletion of the high grade ores in recent years has resulted in a number of new projects focused on lower grade magnetite ores in Algoma-type banded iron formation (or BIF, containing approximately 35 percent Fe).
