Eurodia and Rio Tinto Partner to Redefine Lithium Extraction

­In the rapidly evolving lithium industry, where the global energy transition demands both speed and responsibility, Eurodia is setting new standards with precision-engineered solutions that deliver real-world impact. The French engineering firm has been selected by Rio Tinto, a global leader in mining and critical materials, to supply the industrial lithium extraction unit for Rincon, its Argentine lithium subsidiary. This collaboration further establishes Eurodia’s growing leadership in Direct Lithium Extraction (DLE) and its reputation as a trusted innovator in sustainable industrial solutions.

“At Eurodia, we believe that innovation is the true engine of industrial transformation. Our expertise is in taking cutting-edge laboratory science and turning it into efficient, low-impact industrialised solutions,” says Mathieu Bailly, President of Eurodia.

“Rincon is more than a project, it’s a breakthrough moment for lithium processing, proving that innovation and responsibility can come together to meet the demands of the future.”

Rincon: A milestone for the global lithium industry

With an expected capacity exceeding 50,000 tons per year of lithium carbonate (LCE), the Rincon lithium project—located on its namesake salt flat in Argentina—is a major step forward for the global lithium supply chain. Designed to meet surging demand for lithium while adhering to the strictest environmental standards, Rincon is positioned as a benchmark for responsible resource management. Eurodia’s contribution is central to this vision, delivering a tailored, high-performance industrial lithium extraction unit that maximizes lithium yield while minimizing environmental impact. The project combines precision engineering with process efficiency, ensuring that Rio Tinto’s lithium ambitions are realized with both economic and sustainability objectives in mind.
