Neo Performance Estonia heavy rare earths: supply chain notes for engineers
Reviewed by Joe Ashwell

30 Second Briefing
Neo Performance Materials has produced its first separated terbium and dysprosium oxides from mixed rare earth carbonate at the newly commissioned solvent extraction line at its Silmet plant in Estonia, now running at nameplate capacity. The heavy rare earth output is designed to feed Neo’s sintered magnet plant in Narva, which opened in September as Europe’s first mass-production facility with an initial capacity of 2,000 tonnes per year. Neo is now concentrating on stabilising product purity before ramping to routine production, while maintaining full traceability across its European light and heavy rare earth value chain.
Technical Brief
- Solvent extraction line at Silmet is configured for small-scale operation but currently runs at nameplate.
- Feedstock is mixed rare earth carbonate, implying upstream concentration and carbonate precipitation prior to separation.
- Output products are separated terbium and dysprosium oxides, suitable for direct magnet alloy feed.
- Heavy rare earth separation at Silmet is explicitly integrated with Neo’s Narva sintered magnet plant in Estonia.
- Neo’s value chain now covers both light and heavy rare earth processing, plus finishing into engineered applications.
- Current operational focus is process control to stabilise oxide purity before moving to routine production throughput.
Our Take
Neo Performance Materials shows up in our critical minerals funding coverage via Ottawa’s support package for 30 projects, signalling that the new heavy rare earth output at Silmet is likely to sit within a broader Canada–EU supply chain strategy rather than as a standalone plant upgrade.
With heavy rare earth elements like terbium and dysprosium tagged in only a small subset of the 118 keyword-matched pieces in our database, Silmet’s production move positions Neo as one of the few non-Chinese, industrial-scale suppliers regularly appearing in recent Materials coverage.
Locating heavy rare earth production in Estonia and magnet manufacturing in Narva gives Neo a rare EU-based footprint at a time when most critical minerals funding in our database is still concentrated in Canada and the United States, which may give it leverage in future EU offtake or support schemes.
