Abstract: With the solid waste that produced by electroplating，wet metallurgy，iron and steel production，and used batteries as the research object，a comprehensive analysis of the characteristics and harms of all kinds of solid waste was carried out. The research progress of ferrite materials prepared from solid waste at home and abroad in recent years was reviewed. According to the characteristics of sodid waste，preparation methods of ferrite materials were mainly composed of dry and wet methods.Furthermore，the application and research methods of ferrite materials were briefly introduced，and significance of ferrite materials for solving environmental problems as well as its promoting role in the ferromagnetic material was pointed out.

Key words: solid waste, ferrite, research method
