Regulation of bubble size in flotation: A review
During the flotation process, hydrophobic minerals are transferred to the by bubbles. The size of bubbles has a significant influence on the capture probability of the bubbles and particles, hence affecting the flotation efficiency. Effective regulation of the bubble size is a premise for achieving a controllable flotation index.

1 Froth Flotation – Fundamental Principles
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted ...
