“原地浸取”稀土开采方式对地下水环境的污染风险及应对建议

Pollution Risk of“In-situ Leaching”Rare Earth Mining Method to GroundwaterEnvironment and Countermeasures

离子型稀土矿广泛分布于我国南方地区,“原地浸取”工艺是开采离子型稀土矿的主要技术手段。受经验认知、技术能力、管理水平等多种因素影响,一些企业在实际应用“原地浸取”工艺过程中对矿区地下水环境造成了不同程度的负面影响。本文就离子型稀土矿开采实践中“原地浸取”工艺对地下水环境防控工作可能产生的不利影响进行了梳理,并针对性地提出相关对策建议,以期切实做好矿区地下水环境保护工作,实现经济、生态效益双丰收。

Ionic rare earth minerals are widely distributed in the south of China.In-situ leaching technology is the main technical means to mine ionic rare earth minerals.Influenced by many factors such as experience cognition,technical ability and management level,some enterprises have caused different degrees of negative effects on groundwater environment in mining area in the process of in-situ leaching.In this paper,the possible adverse effects of“In-situ leaching”process on groundwater environment prevention and control in the mining practice of ion-type rare earth mines are sorted out,and relevant countermeasures and suggestions are put forward,with a view to do a good job of groundwater environmental protection in mining areas,to achieve economic and ecological benefits of double harvest.
