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.
