Nth Cycle–IonicRE US rare earth refining JV: process and supply-chain notes for engineers
Reviewed by Joe Ashwell
First reported on MINING.com
30 Second Briefing
Nth Cycle has signed a joint development and licensing deal with Ionic Rare Earths (ASX: IXR) to integrate its modular electro-extraction technology into IonicRE’s rare earth recycling and refining operations, starting at the Belfast facility in Q4 2026. The partners aim to replace the conventional oxalic-acid-based precipitation step with Nth Cycle’s closed-loop, electricity-driven process to produce high-purity rare earth oxides from recycled swarf, creating a refining pathway that bypasses Chinese chemical supply. Nth Cycle’s platform, already applicable to nickel, cobalt and copper, follows a separate 10-year, $1.1 billion offtake agreement with Trafigura signed in March.
Technical Brief
- Precipitation in current rare earth flowsheets depends on oxalic acid reagents produced in China.
- Nth Cycle’s electro-extraction uses electricity to generate in situ chemicals for rare earth conversion.
- Integration targets long-loop recycling of rare earth swarf back to high-purity oxide powders for magnets.
- Partnership claims to remove a “hidden dependency” where even onshore plants still rely on Chinese reagents.
- Nth Cycle positions the platform as applicable across rare earths, nickel, cobalt, copper and other critical metals.
- IonicRE expects lower operating costs from eliminating oxalic acid procurement and associated chemical logistics.
- Belfast plant integration is framed as the first end-to-end refining pathway fully bypassing Chinese chemical supply.
Our Take
Nth Cycle’s 10‑year, $1.1 billion offtake agreement with Trafigura for nickel and cobalt in our database suggests the JV’s rare earth refining capacity in the United States could be underpinned by an existing financing and offtake ecosystem rather than starting from scratch.
Ionic Rare Earths’ role in what it called the Western world’s first end‑to‑end recycled rare earth supply chain for EV motors in the UK–Europe collaboration indicates this US JV is likely to be plugged into established downstream magnet and automotive qualification pathways rather than operating as a standalone refinery.
With China still refining about 90% of global rare earth elements and recent coverage showing stalled diplomatic efforts to alter that balance, a Q4 2026 integration start for Nth Cycle’s technology positions this JV as one of the earlier non‑Chinese refining nodes likely to be scrutinised by defence and EV supply‑chain buyers in the Indo‑Pacific and West.
