In a pivotal development for the North American critical minerals landscape, Rio Tinto gallium extraction has commenced at its Vaudreuil alumina refinery in Saguenay, Quebec, marking the continent’s first successful recovery of primary gallium from bauxite. This milestone, in collaboration with Indium Corporation, positions North America gallium production for a strategic resurgence as global markets face tightening supply conditions.
The first extraction phase occurred at Indium Corporation’s R&D facility in Rome, New York, utilizing bauxite residue from Rio Tinto’s Canadian operations. The pilot process validated the feasibility of capturing gallium—a metal typically found in trace amounts during alumina processing—and now advances to a demonstration phase in Saguenay-Lac-Saint-Jean. Backed by the Quebec government, the facility aims to produce 3.5 tonnes of gallium annually, with commercial expansion targets set at 40 tonnes per year—an estimated 5–10% of current global output.

Scaling North America Gallium Production
Currently, the global gallium market is heavily concentrated, with approximately 600 tonnes produced annually, predominantly in China, Germany, and Kazakhstan. With China imposing export controls on gallium and other critical minerals, North America gallium production has been largely absent—until now.
“We are very proud to announce this significant milestone in our important research and development project to extract gallium from our aluminium operations in Quebec,” said Jérôme Pécresse, Chief Executive of Rio Tinto Aluminium. “Together, through this innovative partnership, Rio Tinto and Indium Corporation strive to strengthen the North American supply chain for gallium, a critical and strategic mineral.”
Ross Berntson, President and CEO of Indium Corporation, emphasized the strategic implications: “This achievement is a major milestone, reflecting our dedication to global industrial needs by ensuring a sustainable supply of gallium. Our joint efforts are positioning North America as a leader in critical material production.”
Why Gallium Matters
Gallium is a cornerstone of modern electronics, used in semiconductors, high-performance integrated circuits, radar systems, LEDs, and a range of civilian and military technologies including electric vehicles and smartphones. Its thermal and electronic properties make it essential for the next generation of chips and power devices.
However, gallium is not mined directly; it is extracted as a byproduct of processing bauxite into alumina or refining zinc ores. This makes supply chains vulnerable to shifts in base metal demand and the policies of dominant producers. The Rio Tinto gallium extraction initiative directly addresses this vulnerability by establishing a homegrown supply route.
Strategic Timing Amid Global Uncertainty
This effort arrives at a time of heightened geopolitical tension and rising industrial demand. The U.S. and Canadian governments have prioritized reshoring and diversifying sources of critical minerals as part of broader strategies to reduce dependency on single-country suppliers.
The Quebec government’s backing underscores the province’s ambition to become a hub for energy transition materials. As North America’s first commercial-scale gallium operation takes root, it could signal a broader reconfiguration of the global gallium market, with North America gallium production stepping onto the international stage.
The next phase—constructing the demonstration plant—will serve as the proving ground for future scaling. If successful, the operation will transform Quebec from a passive consumer of gallium to a vital contributor to North America’s technological self-reliance.
With Rio Tinto gallium extraction now a reality, North America takes a major step toward controlling its own critical mineral destiny. The collaboration with Indium Corporation not only bridges a technological gap but lays the groundwork for a resilient supply chain insulated from overseas disruptions. In a sector where grams matter, tonnes made at home are worth their weight in strategic security.
