  • Iron Ore Department for Energy and Mining

    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.What Are the Different Uses of Iron Ore? (with pictures),Jan 13, 2021· Steel production consumes the vast majority of iron ore produced around the world. To make steel, firms start by crushing and pre-processing ore before smelting it to free the trapped metal with a heat and chemical reaction. This can be used to make so-called “pig iron,” solid blocks of iron that can be further processed.
