Abstract: The paper introduced the structure, benefication principles,SAdvantages and disadvantages of the Cyclonic Static Microbubble Flotation Column. Reviewed it from theoretical research,computer simulation and automation, Structure Optimization Study, combination with flotation column and flotation machine.Summarized the application for metal mine benefication,coal dressing and non-metal mine benfication. Indicated the device would be developing towards large-scale and diversified, and more widely used in the benefication of gold mine. Indicated some research directions and indicated that the device would be more widely used in the benefication.
