Banded iron formations are almost exclusively Precambrian in age, with most deposits dating to the late Archean (2500-2800 Ma) with a secondary peak of deposition in the Orosirian period of the Paleoproterozoic (1850 Ma). Minor amounts were deposited in the early Archean and in the Neoproterozoic (750 Ma). The youngest known banded iron formation is an Early Cambrian …

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.

Iron makes up close to 5% of the Earth's crust. It takes around 1.6 tons of iron ore to produce one ton of steel. The chemical symbol for iron is 'Fe' because of its Latin name Ferrum. We use 20 times more iron (in the form of steel) than all other metals put together. Our iron ore trains are over 2.5km (264 ore cars) long, meaning it can take ...
