Abstract: This paper briefly describes the production and separation technology of ion-adsorption rare earth, materials and products, the possibility and distribution of occupational hazard factors exist during the production processes, occupational disease prevention facilities, prevention articles, health auxiliary clinics and occupational health management. Occupational hazards in the workplace were evaluated by determining the critical control points, including soluble material, extraction, precipitation and firing. The concentration and intensity of occupational hazards in the workplace can be controlled during the normal operation without obvious negative effects on workers.
