REE Processing
Rare earth elements processed from bastnäsite, monazite and ion-adsorption clays.
Beneficiation
Flotation with fatty acid or hydroxamic acid collectors concentrates REE minerals. Gravity and magnetic separation as pre-concentration steps.
Solvent Extraction
Multi-stage mixer-settler circuits separate individual REE using organophosphorus extractants (D2EHPA, PC88A). Achieves >99.9% purity.
