An Evaluation of the Flotation Efficiency of Nano and Micro Bubbles Tailored to Optimize Bubble Size Distribution Using a Kinetic Model

Bubble size is among the most important factors that determines flotation efficiency. The bubble used for flotation varies from nano-bubbles (NB) to micro-bubble (MB). We performed a flotation separation experiment, and then evaluated flotation efficiency by calculating collision-attachment efficiency and the number of NB and MB bubbles using kinetic model. Flotation efficiency was found to be NB
