He studied the effects of solids concentration, frother and depressant dosage on flotation performance of a UG2 ore using a batch flotation cell. The learnings were qualitatively applied to plant operation and decreases in frother dosage, in particular, were found to be beneficial in improving PGM grade through a reduction in entrainment.

However, the separation efficiency of calcite and muscovite in actual ore flotation is not as good as the above flotation results under alkaline conditions, as a part of vanadium-bearing muscovite is lost along with the calcite flotation [13, 14]. This might be due to the differences in the experimental procedure between the actual flotation ...
Similarly, Oyediran et al. [139] and Yu et al. [140] studied the use of an unidentified alkyl and aromatic hydroxamate, along with a commercial aromatic collector (Florrea 7510) for the flotation of the Strange Lake ore (Canada) – a highly complex ore consisting of primarily REE-bearing silicates, such as gadolinite, gerenite, kainosite ...

Abstract. The practice of the flotation of pure gold and gold-bearing ores such as tellurides, aurostibite, kerogen, pyrite, pyrrhotite, copper-gold ores and mixed sulphides is reviewed. The factors which influence the choice of collectors, pH and Eh, are discussed as well as the application of differential flotation.
Flotation studies of quartz and Fe-bearing amphibole samples have revealed that the use of starch as a depressant of Fe-oxides has a hydrophilic effect on the surface of Fe-bearing silicates and significantly decreases their flotation by ether amines. Flotation of these minerals is not possible by primary monoamines in the presence of starch ...
