· The Outlook for Australian Iron Ore Mining in 2024. Like any real relationship, Australia’s love affair with iron ore has been complicated. Since the 1890s, Australians have mined and refined iron ore – in one form or another – to enable a range of industrial pursuits here and overseas. But it hasn’t all been plain sailing.
