rare earth mineral flotation collectors

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  Rare-earth mineral (REM) deposits can be broadly classified into four geological environments: carbonates, alkaline/peralkaline igneous rocks, placers and ion adsorption clays. Apart from ion adsorption clay deposits, which require no mineral processing steps, froth flotation is the most applied beneficiation technique.
