| Abstract: |
| Due to hydrogeological conditions and leakage of leaching mother solution, groundwater environment is seriously threatened during process of in-situ leaching of ionic rare earth mines in South China. To solve the problem of groundwater pollution of ionic type rare-earth ore, Ganzhou Rare Earth Mining Co., Ltd. put forward a new process of groundwater monitoring and end treatment technology basing on Ganzhou rare earth mine hydrogeological conditions, ammonium-free mining technology, and relationship between groundwater and surface water drainage. Focusing on groundwater end treatment in boundary mining area, groundwater pumping and treatment project construction in small watershed was carried out. According to operation effect of groundwater extraction system project, influence of rare earth mining activities on groundwater environment can be effectively controlled. The engineering practice shows that the groundwater extraction treatment technology has advantages of rapid treatment and wide applicability, which provides a reliable way to effectively solve groundwater pollution prevention and control of ionic rare earth mines. |
