An ion-tolerance collector AESNa for effective flotation ...

2021-8-15  The separation of magnesite and dolomite has always been a difficult problem in flotation production, one of the reasons is that the dissolved Ca 2+ ions from dolomite weaken the anionic flotation selectivity. In this study, an ion-tolerance collector, sodium fatty alcohol polyoxyethylene ether sulfonate (AESNa), was used to weaken or eliminate the adverse effects of Ca 2+.
