The world's resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.
