معالجة عناصر الأرض النادرة — الترسيب، التحلل والتجزئة بالحلالات

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.
