离子吸附型稀土矿的浸出工艺及浸取剂研究现状

Research Status of Leaching Technology and Leaching Agent of Ion-adsorption Type Rare Earth Ore

分布于我国南方的离子吸附型稀土矿是我国优势的战略矿产资源,在其开采过程中主要采用浸取技术,但浸出工艺和浸取剂本身,对生态环境存在巨大的污染威胁。旨在对比离子吸附型稀土矿的浸出工艺和浸取剂的基础上,梳理了其存在的主要问题,并提出了改进建议。

The ion-adsorbed Rare Earth Minerals distributed in the south of China are the dominant strategic mineral resources in China.Leaching technology is mainly used in the mining process,but the leaching process and the leaching agent itself pose a huge threat to the ecological environment.On the basis of comparing the leaching process and leaching agent of ion-adsorbed rare earth ore,the main problems existing in the process are sorted out,and some suggestions for improvement are put forward.
