A new production facility in the southwestern French village of Lacq is expected to supply 15 per cent of the global market for heavy rare earths by the end of 2026.

The US$245 million plant is being developed by French company Caremag, a subsidiary of rare earth specialist Carester.

Once operational, it will be Europe’s first large-scale rare earth separation facility, combining recycling of end-of-life equipment with imported mined concentrates.
