Editing Iron ore (section)

===Australia===
[[Geoscience Australia]] calculates that the country's "[[economic demonstrated resources]]" of iron currently amount to 24 [[gigatonne]]s, or {{convert|24000000000|t|abbr=on}}.{{citation needed|date=February 2012}} Another estimate places Australia's reserves of iron ore at {{convert|52000000000|t|abbr=on}}, or 30% of the world's estimated {{convert|170000000000|t|abbr=on}}, of which Western Australia accounts for {{convert|28000000000|t|abbr=on}}.<ref>{{cite web|url=https://www.dmp.wa.gov.au/Investors/Iron-Ore-1482.aspx|title=Iron Ore|work=Government of Western Australia - Department of Mines, Industry Regulation and Safety|access-date=2021-08-06}}</ref> The current production rate from the [[Pilbara]] region of [[Western Australia]] is approximately {{convert|844000000|t|abbr=on}} per year and rising.<ref>{{Cite report |url=https://www.dmp.wa.gov.au/Documents/About-Us-Careers/Stats_Digest_2021-22.pdf |title=Western Australian Mineral and Petroleum Statistics Digest 2021–22 |date=2022 |publisher=Government of Western Australia Department of Mines, Industry Regulation and Safety}}</ref> [[Gavin Mudd]] ([[RMIT University]]) and Jonathon Law ([[CSIRO]]) expect it to be gone within 30–50 years and 56 years, respectively.<ref>{{cite web|url=http://www.abc.net.au/science/articles/2010/07/14/2953402.htm|title=Iron Ore Country|work=ABC Science|last=Pincock|first=Stephen|date=July 14, 2010|access-date=2012-11-28}}</ref> These 2010 estimates require ongoing review to take into account shifting demand for lower-grade iron ore and improving mining and recovery techniques (allowing deeper mining below the groundwater table).
