Abstract
Nanobubbles are employed to bridge microbubbles and non-buoyant particles, thereby creating sufficient capillary forces between the particles and microbubbles such that relatively large, heavy particles can be separated from an aqueous slurry. Nanobubbles are formed on hydrophobic particle surfaces. The microbubbles, which function as collecting air bubbles, form attachments with the particles. The nanobubbles create additional capillary attachment forces between the particles and microbubbles, allowing the microbubbles to rise with the attached particles to the top of the slurry for separation and recovery.
