AI Technical Summary
The bubbles generated by the existing microbubble generators in flotation columns are of varying sizes, which cannot form an ideal adhesion effect with mineral particles, resulting in a decrease in flotation recovery rate and concentrate grade.
A microbubble generator for flotation columns was designed. By coordinating an inclined air inlet pipe, a striking pin, and a plug, and using a pressure spring to control the gas injection, uniform and stable microbubbles are generated, thereby increasing the adhesion probability between minerals and bubbles.
It improves flotation efficiency and concentrate quality, enhances the adhesion between minerals and bubbles, and increases flotation recovery rate and concentrate grade.
