Abstract: With China's mineral resources becoming increasingly more complex, leaner and finer, the development of flotation technology is even more important. The development actuality of flotation technology is summarized, and the innovation of the flotation process, new flotation techniques, development of high effective new column flotation equipment and new flotation reagents, and the new concept of mineral separation are discussed. The future development of flotation technology is prospected.

Key words: Column flotation technique, Flotation reagent, Nonlinear separation
