离子型稀土采选工艺环境影响分析与控制技术

Environmental Impact Analysis and Control Technology of Ion Rare Earth Mining in South of Jiangxi Province

由池浸和原地浸矿两代采选工艺基本原理出发,根据各采选工艺特点逐一分析各工艺对周边环境所造成的影响,并以开采与保护同步进行为原则,从水土保持、氨氮污染、放射性污染及重金属污染四方面分别提出切实的环境影响控制方法。

The mining and processing technique of the southern ion rare earth undergo two stages,pool leaching and in-situ leaching process. At present,in China,to meet the requirement of the resources and environment protection,the pool leaching process was abandoned and the in-situ leaching is promoted. Here,based on the theory of the two stage mining and processing technology,the impacts of ion rare earth mining process on the surrounding environment were analyzed according to the characteristics of mining processes. Moreover,in this paper,taking into account the mining and environment protection,from the point of conservation of water and soil,ammonia nitrogen pollution,radioactive pollution and heavy metal pollution,the practicable methods to control the environmental impacts were put forward.
