TECHNOLOGY

A fundamental departure from conventional solvent extraction.

Selective leaching, continuous ion exchange and simulated moving bed chromatography, integrated into one closed-loop platform that runs continuously and scales on modular skids.

01

THE PROCESS, STAGE BY STAGE

01

Selective leaching

The feedstock is attacked selectively rather than wholesale, transferring target metals out of a complex solid matrix and into solution while leaving as much of the bulk material behind as possible. Less dissolved gangue means less downstream work and less secondary waste.

INPUTSOLID WASTE FEEDSTOCK
OUTPUTLOADED PREGNANT SOLUTION
02

Continuous ion exchange

The loaded solution is captured, concentrated and conditioned on a continuous circuit rather than in discrete batches. This is where the process stops behaving like a laboratory workflow and starts behaving like a production line.

OUTPUTCONCENTRATED METAL LIQUOR
03

Simulated moving bed chromatography

ARM's core platform technology. Rare earth elements are chemically near-identical and notoriously hard to separate; SMB chromatography resolves adjacent elements to high purity in a continuous countercurrent circuit. Once metals are in solution the platform is feedstock agnostic — the same separation train handles very different waste streams.

Finishing & closed loop

Separated streams are finished into high-purity functional oxides and metal co-products suitable for direct use in U.S. manufacturing. Reagents and process water return to the loop, which is what keeps secondary waste — and operating cost — down.

MODULAR SKID SYSTEM

04 · DEPLOYMENT

Modular, skid-mounted, and built to go where the waste already is.

Rather than hauling low-grade material to a single bespoke refinery, ARM's platform is designed to rapidly scale on modular skid-mounted systems sited at the impoundment, the mine, or the recycler. Capacity grows by adding units, not by rebuilding a plant.
