从伴生稀土磷矿中富集与提取稀土元素的研究进展

摘要

The grade of rare earth in rare earth -containing phosphorite is low in nature , but its re-serves are abundant , which offer a high potential for exploitation .Limited to occurrence state of rare earth, crystal structure , and the current scientific and technological level , the industrial recov-ery of rare earth from phosphorite has not been realized till now .This paper systematically summa-rized the different methods of concentration and separation of rare earth from phosphorite , and pointed out the bottlenecks that limiting the utilization of rare earth -containing phosphorite re-source .Furthermore , the possible technologies for recovery were introduced .The solutions to key issues of concentration and separation will provide more new approaches for the development and u -tilization of rare earth resource .%自然界中伴生于磷矿的稀土元素大都品位较低,但因储量巨大,具有很高的开发利用价值.受稀土自身的赋存状态、晶体结构和人类科技水平的限制,从含稀土磷矿中回收稀土元素的工艺尚未达到工业化的水平.系统总结了伴生稀土磷矿富集和分离的方法,指出了伴生稀土磷矿资源开发的技术瓶颈问题,展望了未来从含稀土磷矿中回收稀土可能的技术.含稀土磷矿富集和分离关键技术问题的解决,将为稀土资源的开发利用开辟出新的途径.
