Iron ores of this type are commonly termed the banded iron formation or simply abbreviated as BIF All ore minerals in these deposits are oxides and hydroxid The most common iron ore minerals are hematite, lepidocrocite and goethite while the most common manganese ore minerals are braunite, manganite and hausmannite
In Australia, the majority of iron ore mined comes from banded iron formations in the Pilbara region of Western Australia and on the Eyre Peninsula of South Australia Vale’s Carajás Mine in Brazil is the largest iron mine in the world with vast iron formations and accessory gold, copper and nickel
The primary use of iron ore is in the production of iron Most of the iron produced is then used to make steel Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items
