Neo Performance Materials Silmet (Sillamäe)

Neo Performance Materials' Silmet plant in Sillamäe, Estonia — described by Invest in Estonia as the only industrial-scale and commercially operating midstream (separations) rare earth facility outside of Asia. The operating light rare earth separation line converts rare earth feedstock into high-purity magnetic rare earth oxides; a small-scale heavy rare earth solvent-extraction line was commissioned per Neo's 10 April 2026 release, producing first separated terbium and dysprosium from mixed rare earth carbonate feedstock entirely in Europe. Mappings noted: the light line's mixed-ree-carbonate input and ndpr-oxide output are inferred from source descriptions ('rare earth ore sourced from the U.S.', 'high-purity magnetic rare earth oxides'); heavy-line claims rest on company press only and are marked reported. A rare earth metals line (NdPr metal) was NOT recorded: no verifiable source confirming current rare earth metal production at Silmet was found during this pass.
