The results, obtained with Petronate L agree with Van Lierde’s observations [12]. The best perfor-mance achieved with this collector is 99% at pH = 6. Among the cationic reagents, it was noticed that Armac 18, with a consumption of 500 g/t, doesn’t float barite and could therefore be used in reverse flotation, as also proposed by Ghiani (cit-ed in [11], Carta and Massacci [4]. For the

Investigation on flotation separation of bastnaesite from

01/02/2021 The flotation behavior and separation mechanism of bastnaesite from barite and calcite were evacuated by micro-flotation, zeta potential measurements, FTIR spectra, XPS detection and DFT calculation. Micro-flotation results revealed that OBHA exhibited superior collecting ability to bastnaesite but did not float calcite and barite. A bastnaesite concentrate with around 68.59% REO grade and

Improvement of the Flotation Selectivity in a Mechanical

The results also indicate that a pronounced selectivity effect was obtained from the ultrasonic flotation of both barite and chalcopyrite. The use of ultrasound in the froth remarkably improves the quality of the chalcopyrite concentrate, especially at the shallow froths. Therefore, either effective pulp volume can be increased without sacrificing the separation selectivity or the pulp density

Bastnaesite, Barite, and Calcite Flotation Behaviors with

The flotation of bastnaesite, as a major mineral source of rare earth elements, attracting much attention in the mineral processing field, is challenging owing to the natural flotability of calcium-bearing minerals. To promote the application of flotation, we systematically investigated the flotation behavior of bastnaesite, barite, and calcite, with salicylhydroxamic acid (SHA) as the
