Abstract:With the continuous development of domestic mineral resources, there are more and more refractory ores with low grade, fine grain size and complex mineral composition, which puts forward higher requirements on the performance of mineral processing device. Flotation column is an important flotation device in flotation technology. It has the advantages of small investment, simple structure and high efficiency. It is of great significance to resource utilization. The basic structure, basic working principle and main operating parameters of the flotation column were introduced. The development history and classification of flotation columns were summarized. The basic structure and working principle, advantages and disadvantages, research status and application progress of Jameson flotation column, Cyclonic-static micro-bubble flotation column and Packed flotation column were elaborated. The bubble generator, mathematical model, scale-up and automatic control research progress of the flotation column were summarized. The characteristics and application of several new flotation columns were introduced. Finally, it is pointed out that the future development of the flotation column should be the development and application of bubble generators, combination of comprehensive force fields, mathematical models, scale-up and automation.
Key words: flotation column; flotation; application; bubble generator; progress
