Rare earth metals production using alternative feedstock that eliminates HF

This work reports the metallothermic production of rare earth (RE) Nd metal using NaNdF₄ as an alternative fluoride salt, without HF use or generation, enabling safer, scalable production of critical RE metals for advanced technologies and industry

Solvent-driven fractional crystallization for atom-efficient separation of metal salts from permanent magnet leachates

Rare earth elements are essential to electrified infrastructure and clean energy production. Here, authors show reagent- and energy-efficient separation of lanthanides from secondary feedstock using dimethyl ether-driven fractional crystallization.
