A new collector for rare earth mineral flotation ...
1997-12-1 Due to its high selectivity to rare earth element ions in the weak alkaline region, hydroxamic acid has been used as the collector in rare earth mineral flotation. In our previous papers [9,10], we described experimental studies on the flotation of monazite and bastnaesite from rare earth ores by using a combination of modified hydroxamic acid (MOHA) and proper modifiers.

A review of reagents applied to rare-earth mineral
2020-5-1 The authors found that all three collectors were effective at recovering REM; however, depending on the rare earth cation present in the mineral lattice each collector produced a different flotation response. SHA was most effective at recovering LREM, whereas BHA was most effective at recovering HREM.

Improved Collectors for Flotation of Bastnaesite ...
Bastnaesite is an important mineral because of its abundance and rare earth content. Calcite and barite are the most common gangue minerals associated with bastnaesite. The importance of finding a suitable collector that can be selective against the gangue minerals without heated conditioning is critical to the advancement of the beneficiation of bastnaesite.

Abstract Carboxylates, hydroxamates and organic phosphoric acids are typical collectors used for rare earth mineral flotation. Carboxylates are not selective, while hydroxamates, though selective, require high concentrations to recover a significant amount of rare earth minerals. Other collectors such as organic phosphoric acids, which showed promising rare earth minerals collecting potential ...
