Dec 31, 2018 In 2018, Australia's EDR of iron ore increased by 3 from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4 EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1 , likely due to re-assessment of projects and inactivity in the magnetite industry.
Iron Ore. Iron (Fe) is a metallic element which constitutes about 5 of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ).
