Beneficiation of Low-Grade Rare Earth Ore from Khalzan ...
A dry magnetic separator is typically inefficient in processing fine-grained particles due to the influence of airflow, particle-particle adhesion and particle-rotor adhesion, so a wet high-intensity magnetic separator (WHIMS, L-4, Eriez Co. Ltd., Chiba, Japan) (Figure 2b) was adopted for recovering REEs from fine fractions (−212 + 106, − ...
