Rio Tinto Explores Gallium Extraction in Canada Amid Global Supply Shift

Rio Tinto

Global mining giant Rio Tinto is investigating the feasibility of extracting gallium from its operations in Canada, positioning itself to play a critical role in the North American supply chain for this strategically significant metal. The company plans to establish a demonstration plant in Quebec's Saguenay-Lac-Saint-Jean region, which could eventually produce up to 40 million tonnes of gallium annually, accounting for 5-10% of global output.

Leveraging Bauxite for Gallium Extraction

The gallium extraction initiative focuses on utilizing the gallium present in the bauxite ore processed at Rio Tinto's alumina refinery in Quebec. This approach highlights the company’s innovation in valorizing existing materials in its production processes.

During the project's initial phase, Rio Tinto will evaluate the technology required to extract gallium. If successful, the company aims to build a demonstration facility capable of producing 3.5 million tonnes annually in its early stages, with plans to expand capacity as demand grows.

Gallium, a critical metal primarily used in the semiconductor and solar panel industries, has seen a surge in strategic importance following China's decision to restrict exports of gallium and other vital minerals to the U.S. As the world's largest gallium producer, China's actions underscore the need for alternative sources, making Rio Tinto's initiative a pivotal development.

Strengthening North American Critical Mineral Supply

Rio Tinto’s project aligns with broader efforts to bolster the North American supply chain for critical and strategic minerals, ensuring a more resilient and independent supply network. Rio Tinto Aluminium’s chief executive, Jerome Pecresse, emphasized the project’s role in addressing geopolitical and supply chain challenges in the global critical metals market.

With the growing reliance on gallium for advanced technologies, including semiconductors and renewable energy solutions, Rio Tinto’s project represents a significant step forward in diversifying the global supply of this vital resource.
