Mining and processing hematite and magnetite ores . ore and involves magnetic separators to extract the magnetite and produce a concentrate. . Hematite ores dominate the world production of iron ores and are sourced . Australia has Accessible EDR (AEDR) of iron ore totals 44 650 Mt, of which 91% occurs in WA. Top.
The principal iron ores are hematite (Fe2O3) and magnetite (Fe3O4). . undergo a second stage of processing that relies on the magnetic properties of the ore and involves magnetic separators to extract the magnetite and produce a concentrate. . Table 3.21 Australia's resources of iron ore and contained iron with world.
Iron ores are rocks and minerals from which metallic iron can be economically extracted. . Indeed, it has been argued that iron ore is "more integral to the global .. to mine and process as they require less beneficiation due to the higher iron . is left behind when the resultant powder is passed under a magnetic separator.
