微生物技术在稀土资源利用中的研究进展

Research Progress of Microbial Technology in Utilization of Rare Earth Resources

稀土是不可再生宝贵资源,广泛应用于生产生活中。针对目前稀土开采仍较粗放且缺乏对稀土有效回收这一现状,关注了微生物技术在浸出低品位尾矿和回收废弃物中稀土的优势,并着重介绍了微生物浸出稀土及相关机理研究,主要包括微生物浸出、回收及富集和纯化稀土。简述了微生物浸出稀土存在的主要缺陷,结合已有研究成果展望了微生物浸出技术在稀土领域研究方向及其面临的挑战。

Rare earths are non-renewable and valuable resources that are widely used in production and life.In view of the current situation of extensive rare earth mining and lack of effective recovery of rare earth,the advantages of microbial technology in leaching rare earth from low-grade tailings and recovering rare earth from waste are focused,and the research on microbial leaching of rare earth and related mechanisms are emphatically introduced,mainly including microbial leaching,recovery,enrichment and purification of rare earth.The main defects of microbial leaching of rare earth are briefly described.The research direction and challenges of microbial leaching technology in rare earth field are prospected based on the existing research achievements.
