Abstract: Combining with development of exploitation process of ionic-type rare earth ore, environmental problems caused by exploitation of ionic rare earth ore were summarized, including geological disasters of large area of vegetation damage, serious soil erosion and landslides and debris flow, soil salinization, and pollution of surface water and underground water.The measures for environmental pollution control were introduced from three aspects of pollution control, project management and ecological restoration.Among these, pollution control includes distribution of clear water and wastewater, artificial anti-seepage bottom, class three monitoring fluid-collecting system,dynamics long-term monitoring network of groundwater and ammonia-nitrogen wastewater treatment.Project management includes land consolidation, drainage system and other projects.Ecological restoration consists of soil improvement, vegetation restoration and microbial remediation techniques.

Key words: Ionic-type rare earth mine, Environmental problems, Treatment methods
