Maglut Heavy Industries rare earth strategy: ARC-1 process insights for mine planners
Reviewed by Tom Sullivan

30 Second Briefing
Maglut Heavy Industries is developing a chromatography-based rare earth processing platform at its pilot-scale Long Beach, California facility, reporting 99.9%+ purity for individual rare earth oxides using its ARC-1 water-based separation process. The company designs and manufactures its own resin and ligand systems, aiming for globally competitive costs versus conventional solvent extraction as US defence contractors face January 2027 rules to eliminate Chinese rare earth magnets. A demonstration-scale plant is planned to be fully operational by August 2027, producing commercial rare earth oxides and potentially expanding to other critical minerals.
Technical Brief
- Process is fully water-based, eliminating organic solvent extraction circuits and associated fire and vapour controls.
- Pilot validation used “real-world feedstock”, implying tolerance for variable concentrate chemistries rather than synthetic test solutions.
- Maglut reports active negotiations both upstream (feedstock supply) and downstream (oxide offtake), signalling integrated supply-chain planning.
Our Take
USA Rare Earth’s presence in this Long Beach–centred rare earths story links directly to its US$2.8 billion Serra Verde deal in Brazil, suggesting Maglut’s ARC‑1 separation capability could become part of a cross‑border supply chain spanning ionic clays in Goiás and downstream processing in the United States.
With China still controlling about 90% of global rare earth separation and refining, and having already placed MP Materials and USA Rare Earth on its export control list, a 99.9% purity ARC‑1 process in California would give US‑based operators a non‑Chinese pathway for high‑spec oxides that defence and EV customers increasingly demand.
The 2027–2030 ramp‑up window for Maglut’s pilot‑scale facility overlaps with new US Department of Defense and State Department support seen in our coverage for projects like Harena Rare Earths, signalling that early technical validation in Long Beach could be well‑timed for accessing US-backed offtake or financing programmes for critical minerals.
