Siderite is a mineral composed of iron(II) carbonate (FeCO 3).Its name comes from the Ancient Greek word σίδηρος (sídēros), meaning "iron".A valuable iron ore, it consists of 48% iron and lacks sulfur and phosphorus.
Elemental iron is virtually absent on the Earth's surface except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Although iron is the fourth most abundant element in Earth's crust, composing about 5% by weight, [4] the vast majority is bound in silicate or, more rarely, carbonate minerals, and smelting pure iron from these minerals would require a prohibitive ...

Hope 4 is about 30 kilometres (19 mi) north of Newman, and had a reserve of 162Mt as at 2016. Production at Baby Hope started in 2018. [1] The Hamersley Range, where the mine is located, contains 80 percent of all identified iron ore reserves in Australia and is one of the world's major iron ore provinces. [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.
Construction at South Flank began in July 2018, the Mine is already producing ore and is partially complete, once opened it will become the largest processing facility in Western Australia. BHP is the second-largest iron ore mining company in the Pilbara, behind Rio Tinto and ahead of the Fortescue Metals Group . [ 2 ]
The Pilbara operations accounted for almost 13 percent of the world's 2009 iron ore production of 1,590,000,000 tonnes (1.56 × 10 9 long tons; 1.75 × 10 9 short tons).
