摘要
多年来，对离子型稀土矿一直采用传统的露采池浸工艺开采，残留了大量的矿石，充分回收这些资源具有重要意义。介绍了残矿产生的原因及特征，重点阐述了利用原地浸析采矿方法回收残矿的技术措施，并对其经济效益及社会效益作了分析。
Ion type rare earths have been recovered by the surface mining pool leach process, resulting in lots of remnant ores. The recovering of the mineral resources is of great importance. This paper describes their forming causes and characteristis, and especially the technical schemes for recovering them by in situ leaching. In addition the authors analyse their economic benifit and social effect.
