  Flotation-magnetic separation for the beneficiation of rare …

  201841 · 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 ...

  Influence of magnetic fields on calcium carbonate scaling in aqueous ...

  201811 · Three important conclusions regarding the effect of magnetic field treatment upon scale formation in calcium bicarbonate solutions were reached. Firstly, the ratio of calcium to bicarbonate plays a key role in determining how magnetic fields influence scale formation, whether promoting or inhibiting it. Solutions containing high concentrations of …
