The mining technology of southern ionic rare earth ore has experienced the evolution of pool leaching and heap leaching, and the in-situ leaching technology is currently used. In-situ leaching mining technology has the advantages of not damaging surface plants and producing tailings, but there are still risks such as landslides, pollution of surface water and shallow groundwater. Based on the analysis of in-situ leaching mechanism and process flow, the key points of pollution prevention and environmental protection management in the design stage, construction stage, production stage and later production stage of ionic rare earth mining were introduced. Practice has proved that by taking reasonable pollution prevention and control measures, the disturbance of the mining of ionic rare earth mines on the surface water, groundwater, soil and other ecological environment in the mining area and surrounding areas is controllable, and the green development of ionic rare earth mines is realized.
