Abstract: To promote the enterprises of production of ion-adsorption rare earth ore separation water resources recycling and waste water treatment and reuse, water intake quota management in enterprises should be strengthened effectively. The water intake of 14 ion-adsorption rare earth ore separation production enterprises affiliated to China's six major rare earth groups was investigated, through the analysis and research of the investigation data, the water intake quota of existing enterprises, newly built and expanded enterprises and advanced enterprises in ionic rare earth ore smelting and separating production was determined.Among them, the water intake quotas of enterprises producing 5~9 rare earth products with purity above 99% were 80, 70, 60 m³/t-REO respectively, while those producing 10 or more products were 90, 80 and 70 m³/t-REO respectively.
