Abstract: The increasing demand for high quality iron concentrate in iron and steel industry has promoted the rapid development of magnetite column cleaning equipment. The research status of magnetite column cleaning equipment is reviewed, and the problems of the traditional magnetite column, such as narrow range of particle size for feeding, poor recovery effect, large water consumption and low treatment capacity are analyzed in this paper. The upgrade research of composite magnetic field, structural optimization, permanent magnetization and control system has improved the TFe grade of magnetite concentrate and recovery rate of fine high-magnetic minerals, with the increase of the processing capacity of the equipment and decrease of the water consumption, which simplified the production process and improved the production efficiency. It is pointed out that the main development direction of magnetite column cleaning equipment in the future is the fine sorting based on different components of magnetite, and the research of efficient and intelligent sorting equipment and technology.

Key words: magnetite, cleaning with magnetic column, magnetic system, structure, permanent magnetization, intelligent control
