摘要
针对离子型稀土开采提取过程中极易产生的低浓度离子型稀土废水难处理、污染环境等问题,对近5 a来国内外低浓度离子型稀土的富集回收技术进行了总结,综述了反渗透、溶剂萃取、离子交换、吸附以及沉淀等多种不同稀土资源回收技术的作用原理和研究进展,分析了各类稀土资源回收技术的优劣势,并提出了未来低浓度稀土资源绿色高效安全回收技术的重点研究方向,为离子型稀土资源的高效开发利用研究提供有益参考。
Aiming at the problems of difficult treatment and polluted environment of low concentration ionic rare earth wastewater which is very easy to be produced during the extraction process of ionic rare earth mining,it has made a comprehensive summary of the enrichment and recovery technologies of lowconcentration iron-type rare earth both domestic and foreign for the recent five years.It also summarizes the working mechanisms and recycling developments of various different recycling technologies such as reverse osmosis,solvent extraction,ion exchange,adsorption and sedimentation,the advantages and disadvantages of various rare earth resources recovery technologies are summarized.It is aimed to provide necessary reference for the research on the green,efficient and safe recycling technology development and utilization oflow-concentration ion-type rare earth resource,andprovides a useful reference for the efficient exploitation and utilization of ionic rare earth resources.
