La Rochelle Plant Begins Neodymium and Praseodymium Oxide Output
Belgian chemical company Solvay has officially begun refining neodymium and praseodymium oxides for permanent magnets at its La Rochelle facility in France. This expansion marks the company's first step into magnet-grade rare earth oxide production, positioning it as a key player in the European supply chain for critical magnet materials.
The La Rochelle plant, operational since 1948 and owned by Solvay since 2011, previously focused on refining cerium and supplying sectors such as automotive catalysts and healthcare. The new line now enables production of neodymium-praseodymium (NdPr) oxides, with potential for separating dysprosium and terbium in the future, according to a Solvay spokesperson.
Europe Strengthens Rare Earth Independence
This development comes amid growing urgency in the West to reduce dependency on Chinese rare earths. China’s recent export restrictions on heavy rare earths and magnet materials—announced in response to new U.S. tariffs—have underscored the fragility of global supply chains. These restrictions follow similar export limits on gallium and tungsten, which led to global supply disruptions and price surges.
Solvay’s La Rochelle initiative aligns with Europe’s strategic goal of securing a domestic rare earth supply chain. The company aims to meet 30% of Europe’s demand for magnet-focused rare earth oxides by 2030. Solvay also emphasized the significance of this production line as a major milestone in its contribution to Europe's energy and industrial independence.
Securing Supply Through Recycling and Strategic Partnerships
To ensure consistent feedstock, Solvay has partnered with Canadian firm Cyclic Materials to source recycled mixed rare earth oxide. Additionally, Solvay has a strategic alliance with rare earths services company Carester, which is developing the Caremag refining plant in Lacq, France. These partnerships help diversify sourcing and reduce reliance on virgin materials or imports.
The Metalnomist Commentary
Solvay’s magnet-focused rare earth production is a timely and strategic response to rising geopolitical tensions and critical mineral nationalism. As Western economies scramble to localize high-tech material supply chains, Solvay’s effort not only bridges a crucial gap in refining capacity but also sets a precedent for integrating recycling and partnerships into Europe’s rare earth future.
