Abstract:After the optimization of the self-separation copper process in Chengmenshan Copper Mine, the flotation column was introduced to recover copper concentrate. Flotation column contributes to the improvement of mine flotation efficiency because of its excellent and efficient inflation efficiency. As the core part of flotation column, the gas-charging performance of bubble launcher directly affects the working efficiency of flotation column, and has a great influence on flotation indexes. By analyzing the bubble distribution of bubble launcher of flotation column, the study on the inflation performance of bubble launcher of flotation column is carried out, and the layout of bubble launcher of flotation column is optimized, which can not only improve the flotation efficiency of flotation column, but also provide reference value for the application and research of flotation column bubble launcher.
