Top Iron Ore Producers in 2025: Countries, the Big Four Miners and Canada's Labrador Trough

Who are the top iron ore producers? By country, the answer is concentrated: the U.S. Geological Survey estimates that the world mined about 2.6 billion tonnes of usable iron ore in 2025, and Australia alone supplied 980 million tonnes of it (USGS Mineral Commodity Summaries 2026, iron ore). By company, the best-known names are Rio Tinto, Vale, BHP and Fortescue, each reporting more than 200 million tonnes a year. Below are the latest figures for both, then Canada's producers.

Top iron ore producing countries, 2025 (estimated)

USGS figures are usable ore in million tonnes, with 2025 estimated (USGS):

On these estimates, Australia accounts for roughly 38% of world usable ore, and Australia and Brazil together for about 54%. India posted the largest increase, from 282 to 310 million tonnes. The iron content column matters as much as tonnage, because grade varies widely. China's 290 million tonnes of usable ore contain an estimated 180 million tonnes of iron, while Canada's 69 million tonnes contain 41 million (USGS).

U.S. output fell 16% to an estimated 38 million tonnes after one operator idled two Minnesota mines in March 2025 to reduce stockpiles (USGS).

The big four iron ore miners

The companies report on different bases and fiscal years. Treat the table below as a scale comparison, not a strict ranking.

Vale said its 2025 iron ore output of 336 Mt was its highest since 2018. Its S11D complex hit a record 86.0 Mt, and the company guided to 335–345 Mt for 2026 (Vale 4Q25 production report, SEC).

Rio Tinto's Pilbara shipments slipped 1% in 2025, and its 2026 Pilbara sales guidance is 323–338 Mt. The bigger change is Simandou in Guinea, which made its first shipment in Q4 2025. Rio has guided to 5–10 Mt of Simandou sales in 2026, against a stated mine capacity of 60 Mtpa (Rio Tinto Q4 2025 operations review, SEC).

BHP reported record iron ore production of 265 Mt in fiscal 2026, with Western Australia Iron Ore (WAIO) also at a record. It expects 260–272 Mt in fiscal 2027 (BHP operational review, July 2026, SEC).

Fortescue passed 200 Mt of annual shipments for the first time, including 9.0 Mt of Iron Bridge magnetite concentrate. Its hematite C1 cost was US$18.74/wmt. Fortescue also flagged an expected non-cash impairment of about US$525 million on Iron Bridge after revising that project's ramp-up schedule, and it guides to 197–207 Mt for fiscal 2027 (Fortescue June 2026 quarterly report).

For investors, the guidance ranges point to flat volumes for the incumbents. Growth is coming from new supply such as Simandou and from India rather than from the established Pilbara and Brazilian systems.

Canada's producers and the Labrador Trough

Canada ranks seventh on the USGS table, with an estimated 69 Mt in 2025. It was also the second-largest source of U.S. iron ore imports in 2021–24, at 21%, behind Brazil's 58% (USGS).

• Iron Ore Company of Canada (IOC), reported by Rio Tinto, produced 15.9 Mt of pellets and concentrate in 2025 on a 100% basis (9.3 Mt Rio share), down 1%. Rio blamed the weaker fourth quarter on pit health and equipment reliability (Rio Tinto).
• Champion Iron (TSX: CIA, ASX: CIA) produced a record 14,168,700 wmt of high-purity 66.2% Fe concentrate at Bloom Lake, on the south end of the Labrador Trough near Fermont, Quebec, in the year to March 31, 2026. That was up 2% (Champion Iron FY2026 annual report). Its DRPF project is designed to upgrade up to half of Bloom Lake's capacity to direct-reduction pellet feed grading up to 69% Fe. The company is also advancing the Kami project in southwestern Labrador with partners Nippon Steel and Sojitz (Champion Iron Q4 FY2026 release).
• ArcelorMittal Mines Canada (AMMC) is reported together with ArcelorMittal Liberia. The two combined produced 35.3 Mt in 2025, and ArcelorMittal's release does not break out the Canadian share (ArcelorMittal Q4 2025 results, SEC).

For Canadian producers, the investment case rests more on grade than on volume, and premiums for quality are not guaranteed.

Prices

USGS puts the Tianjin 62% Fe fines price at an average of $99.07/t in the first nine months of 2025, down from $112.07 a year earlier (USGS). Realized prices in the producers' latest fiscal years were US$84.56/wmt at BHP and US$91/dmt for Fortescue hematite (BHP; Fortescue). With volumes broadly flat, unit costs and product quality are what separate the producers.
