Rio Tinto has reported a new annual production record for its bauxite operations in 2025.
In its fourth quarter results, Rio Tinto reported 62.4 million tonnes (Mt) of bauxite produced in 2025, a 6% increase compared to 2024.
Rio Tinto CEO, Simon Trott, said: “Our operations delivered exceptional production performance, both on a quarter-on-quarter and full year basis, as we leverage our strong foundation of operating excellence and project delivery across our portfolio.
“A step change in bauxite production through the year once again highlights the ongoing maturation of our operational excellence.
“Implementation of our stronger, sharper, simpler way of working continues, and is delivering results and creating value.”
In the fourth quarter alone, bauxite production remained robust at 15.4 Mt, supported by high plant utilisation rates at the Amrun mine in Australia.
The record output was driven by the ongoing implementation of the Safe Production System and stable operating performance across assets.
Alongside bauxite, the company saw consistent and continued strength across its aluminium and alumina operations in 2025.
Alumina production also grew, reaching 7.6 Mt, marking a 4% increase over 2024.
Primary aluminium production also saw a marginal increase, rising by 3% across the year.
Going forward, Rio Tinto’s low-carbon AP60 aluminium smelter expansion in Quebec, Canada, remains on track, with first hot metal and commissioning expected in Q1 2026.
This project will add 160,000 tonnes of primary aluminium capacity per annum.
