Port Hedland is one of the largest iron ore loading ports in the world and the largest in Australia. In 2022, it had the largest bulk cargo throughput in Australia. With the neighbouring ports of Port Walcott and Dampier, Port Hedland is one of three major iron ore exporting ports in the Pilbara region of Western Australia.
William Austin Burt discovered iron ore in the Marquette Range near Negaunee, Michigan in 1844. Iron ore was discovered on the Menominee Range in 1867 and on the Gogebic Range in 1884. It was first discovered in Minnesota on the Vermilion Range in 1885, the Mesabi Range in 1890, and the Cuyuna Range in 1903. [2]
Limonite (/ ˈ l aɪ m ə ˌ n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)·nH 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.
Of the iron ore exported, 38.5% of the volume was iron ore pellets with a value of $2.3 billion, and 61.5% was iron ore concentrates with a value of $2.3 billion. [40] 46% of Canada's iron ore comes from the Iron Ore Company of Canada mine, in Labrador City, Newfoundland, with secondary sources including the Mary River Mine in Nunavut. [40] [41]
Although channel iron deposits are typically low-grade at 53% to 57% Fe in-situ, they are composed of goethite-limonite which are hydrated iron oxide species. Ore typically contains around 8% to 12% water, and <5% SiO 2, and <3% Al 2 O 3. The hydrous iron oxides can be calcined, and the CID ore on a volatile-free basis is around 63% Fe or more.

Iron formations can be divided into subdivisions known as: banded iron formations (BIFs) and granular iron formations (GIFs). [ 3 ] The above classification scheme is the most commonly used and accepted, though sometimes an older system is used which divides iron-rich sedimentary rocks into three categories: bog iron deposits , ironstones , and ...
