magnet- and separation-critical rare earths targeted by one selective platform

The challenge

Why it matters

Separation and refining, not mining, is where rare-earth value and strategic risk concentrate, and that capacity sits overwhelmingly in one country.

The solution

How it works

Active, selective magnetic nano-robots extract rare-earth ions from brines, leachates, tailings slurries and industrial process waters, then release the captured material for concentration and refining. The capture media is designed for reuse in a closed loop, scaling from suspension to a skid-mounted magnetic module to a containerised unit at the feed.

Capabilities

What it does

Feedstocks include ore and tailings slurries, brines and waste streams, water and wastewater and recycling liquors. Performance targets require feed-specific pilot validation.
