— Bulk flotation is generally performed at around pH 9, while Cu-Ni separation is performed at higher pH, around 11. In some cases, flotation is operated at saturated lime pH condition (i.e. pH > 12) to strip the collector from the surface of pentlandite. Cyanide or dextrin can also be used to help depress pentlandite (Lawson et al., 2014). The ...

— Section snippets Materials. The surfactant, Methyl isobutyl carbinol (MIBC), supplied by Alfa Aesar (99% C 6 H 14 O, Product No. A13435), was chosen for this study as it is widely used in flotation plants. Moreover, MIBC can improve the stability of bubbles and has little effect on the wettability of graphite surfaces (Miller et al., 1983).
