An improvement on selective separation by applying ...

It has been known that the power ultrasound is used as a pretreatment and rarely applied as a simultaneous method to improve grade and recovery during froth flotation processes. this work aimed at investigating the impact of simultaneously used ultrasonic waves under variant operating configurations on the flotation of representative porphyry copper ore during rougher and re-cleaner stages.

Effect of copper ions on the flotation separation of ...

Jan 01, 2018· in the flotation separation of cu-mo bulk concentrate, copper ions were ubiquitous after regrading and were mainly in the form of copper hydroxides, i.e., cu(oh) + and cu(oh) 2 in weakly alkaline conditions. accordingly, after the adsorption of these hydrophilic species, the zeta potentials of both chalcopyrite and molybdenite surface dramatically changed from negative to …
