    Rio Tinto gallium pilot in Quebec: process and residue value notes for engineers

    March 3, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    Rio Tinto is proceeding with construction of a pilot plant in Quebec to extract primary gallium from its alumina refining process, backed by a conditionally approved contribution from Natural Resources Canada under the Global Partnerships Initiative. The project, developed with Indium Corporation, follows successful first gallium extraction in May 2025 using process streams from Rio Tinto’s alumina refineries. If scaled, the technology could turn refinery residue and intermediate liquors into a new critical metal stream without major changes to existing Bayer process infrastructure.

    Technical Brief

    • Pilot-scale operation is intended to validate continuous extraction performance and gallium recovery efficiency under refinery operating conditions.
    • Successful piloting would allow retrofitting of similar extraction circuits across Rio Tinto’s wider alumina refinery network.
    • By valorising refinery residues, the flowsheet aims to reduce waste tonnages requiring storage or long-term management.
    • Outcomes will inform whether gallium can be treated as a routine by-product stream in alumina refinery design and debottlenecking studies.

    Our Take

    In our database, gallium appears only in a small subset of the 1109 Mining stories, signalling that Rio Tinto’s Canada‑based gallium work is still at the niche end of critical‑minerals coverage compared with mainstream battery metals.

    The related March 2026 item on Rio Tinto’s conditional C$18.95 million support from Natural Resources Canada’s Global Partnerships Initiative suggests this Quebec gallium pilot is being positioned as a strategic by‑product stream from alumina and bauxite operations rather than a standalone mine development.

    With Indium Corporation linked in the related coverage alongside gallium and alumina, this pilot in Quebec could give Rio Tinto an early foothold in supplying semiconductor‑grade minor metals from existing alumina infrastructure, a route other aluminium producers in our coverage have not yet publicly pursued in North America.

    MetalQuest’s Lac Otelnuk iron project: economics and infrastructure lens for engineers

    MetalQuest Mining’s Lac Otelnuk project in northern Quebec hosts 4.9 billion tonnes of proven and probable reserves grading 28.7% Fe, with a 2015 feasibility study outlining an 11.6 km by 2.8 km open pit, post-tax NPV of US$5.24 billion (8% discount), IRR of 13% and capital costs of about US$14.2 billion. The study forecasts 68.5% Fe concentrate with 0.02% P and 2.95% SiO₂, positioning it for DRI-based low-emission steelmaking using Quebec hydro power. Infrastructure remains the critical constraint, with a previously proposed 755 km concentrate slurry pipeline to Sept-Îles now likely to be replaced by road and rail, and MetalQuest seeking a major partner ahead of a new feasibility targeted for 2030.

    XCMG–Codelco MoU: haul fleet competition and design notes for Andean copper mines

    XCMG has signed a memorandum of understanding with Chilean copper major Codelco in Santiago on 3 March, following Codelco Chairman Máximo Pacheco’s visit to XCMG’s Xuzhou manufacturing base in February. The agreement, signed by XCMG Vice President Liu Jiansen and Codelco Chief Procurement Officer Mauricio Acuña, centres on expanding supply of large-scale mining equipment and support services to Codelco’s open-pit and underground copper operations. For engineers, the deal signals intensifying competition with established OEMs on haul trucks, loaders and drilling fleets in high-altitude Andean conditions.

    Oklahoma critical minerals refining push: infrastructure and power notes for engineers

    Oklahoma is positioning itself as a critical minerals processing hub rather than a mining state, anchored by Emirates Global Aluminium’s proposed US$4 billion primary aluminium smelter at the Port of Inola on the McClellan–Kerr Arkansas River system and backed by surplus low‑cost power from wind and natural gas. USA Rare Earth is building a vertically integrated rare earth magnet plant in Stillwater with about US$1.6 billion in public and private funding, while Stardust Power (NASDAQ: SDST) is advancing a lithium refinery in Muskogee with Sumitomo offtake and key permits secured. The cluster targets defence and aerospace demand around Tinker Air Force Base and other installations, aiming to plug the “missing middle” between raw mineral supply and finished components.
