Abstract: Based on practical situation of rare earth industrial chain, production process and rare earth materials that could produce solid wastes on batch were discussed. Formation cause, formation volume, composition analysis and comprehensive utilization of the solid wastes of rare earth hydrometallurgy slag, electrolysis slag, Fe-based rare earth permanent magnetic materials, Co-based rare earth permanent mag-netic materials, rare earth hydrogen storage materials, rare earth polishing powders and rare earth catalysts were comprehensively introduced.Besides, some suggestions on treatment and administration on rare earth solid wastes were put forward.
