The Iron Range is collectively or individually a number of elongated iron-ore mining districts around Lake Superior in the United States and Canada. Much of the ore-bearing region lies alongside the range of granite hills formed by the Giants Range batholith . [ 1 ]
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.

Western Australia is the world's largest iron-ore producer (34% of the world's total), and extracts 66% (6.9% of world production) of Australia's 306 tonnes (9.8 million troy ounces) of gold in 2022. [54] It is a major world producer of bauxite, which is processed into alumina at four refineries providing 11% of total world production.
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 ...
