Development and application of complex Flashing-field magnetic cleaner

In order to enhance the quality of iron concentrate from magnetic separation, reverse-flotation technology is often applied in an iron ore dressing plant.However, this technology has disadvantages in terms of operating cost,energy consumptionand environmental protection(Zhao, Wu& Wang,2005).Developing innovative equipment to process magnetite ore more-effectively is a way to get rid of these disadvantages of reverse flotation and improve the quality of iron concentrate.This paper describes the development of Complex Flashing-Field Magnetic Cleaner,a new kind of equipment based on the principle of combination of separation in magnetic field and separation in gravity field(Hao & Jiang, 2002).This innovative equipment possesses a tailor-made magnetic system and has the characteristics of a magneticfieldwhich can strengthen the formation of magnetic agglomerations and the dispersion of gangue mineralsto improvethe quality of separation.The automatic control system developed specifically for this equipment can further increase the accuracy of separation and stabilize the process.
