Flotation of rare earth minerals from silicate–hematite ...

2016-4-1  The flotation of rare earth (RE) minerals (i.e. xenotime, monazite-(Nd), RE carbonate mineral) from an ore consisting mainly of silicate minerals (i.e. primary silicate minerals and nontronite clay) and hematite was investigated using tall oil fatty acids (Aero 704, Sylfat FA2) as collector. The RE minerals are enriched with Fe.

2018-4-1  Flotation-magnetic (FM) separation is a newly-developed technology for the economic recovery of rare earth elements from the Dalucao ore. The FM process selectively agglomerates the rare earth particles while separating them from gangue minerals by bubble flotation. The agglomeration of fine bastnaesite particles has been observed by optical ...

A review of reagents applied to rare-earth mineral flotation

2020-5-1  Xia et al. compared the use of three different aromatic hydroxamates (BHA, SHA and H 205) in the flotation of the Nechalacho ore. 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.
