A review of reagents applied to rare-earth mineral flotation

2020-5-1  While most laboratory work to date investigating the flotation of minerals with hydroxamate collectors focuses on the use of alkyl hydroxamates, a modified naphthyl hydroxamate (known as H 205) has been widely used to process Chinese bastnӓsite ores, producing rare-earth oxide (REO) concentrates with grades above 50% [13,119,127].

A new collector for rare earth mineral flotation ...

1997-12-1  A new collector for bastnaesite flotation - modified hydroxamic acid (MOHA) has been developed through several years laboratory research. The experimental results of flotation of pure bastnaesite mineral and rare earth ores, and the application experience in flotation plants showed that MOHA is an efficient collector for bastnaesite flotation.

A review of reagents applied to rare-earth mineral flotation

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.
