Rare Earth Processing Types

Physical beneficiation of raw ore to produce a mineral concentrate suitable for hydrometallurgical processing.

Hydrometallurgical breakdown of mineral concentrates using acid or alkaline digestion to produce a mixed rare earth carbonate or chloride solution.

Solvent extraction (SX) and ion-exchange processes that isolate individual rare earth elements from mixed feedstocks into high-purity oxides. The most technically demanding and geopolitically sensitive step in the value chain.

Further purification of REE compounds to meet exacting specifications for downstream metal and magnet producers.

Electrolytic or metallothermic reduction of purified REE oxides or fluorides into metals and alloys ready for magnet production.

Production of high-performance sintered or bonded NdFeB permanent magnets - the critical component in EV motors, wind turbines, and defence systems.

Assembly of REE-containing components - phosphors, magnets, and capacitors - into consumer devices.

Manufacturing of electric vehicle drivetrains and traction motors, which are among the largest consumers of high-performance NdFeB magnets.

Production of permanent magnet direct-drive wind turbine generators, each requiring several hundred kilograms of high-coercivity NdFeB magnets.

Recovery of rare earth elements from end-of-life products and manufacturing scrap, creating a circular supply loop that reduces primary extraction dependency.

Small-scale demonstration and research facilities testing novel processing routes before commercial scale-up.

Strategic storage, blending, and distribution of REE materials across the supply chain, including bonded warehouses and trading hubs.

Seabed mineral extraction targeting polymetallic nodules and seafloor massive sulphide deposits containing rare earth elements.

Shared-infrastructure processing hubs that serve multiple mining companies, offering toll processing across separation, cracking, and refining stages.
