Cavitation nanobubbles enhancing the flotation of microfine ilmenite and associated fundamentals.

ABSTRACT: Nanobubbles (NBs) have been extensively utilized in mineral flotation, acting as secondary collectors to improve flotation efficiency. However, the fundamental interaction mechanisms between NBs and flotation collector remain unclear. In this study, NBs generated through hydrodynamic cavitation were introduced into the flotation of microfine ilmenite. With octyl hydroxamic acid (OHA) as the flotation collector, the effects of NBs on the flotation of microfine ilmenite were systematically investigated using a series of techniques. The results show that NBs not only improve the flotation recovery and flotation rate of microfine ilmenite, but also significantly lower OHA consumption while maintaining comparable recovery to the flotation without NBs. The measurements of the apparent size of il
