摘　　要：稀土元素因其独特的性质及其在工业中的应用价值而受到关注。本文介绍了稀土元素特点与稀土资源概况,阐述了稀土金属冶金现状及工艺体系,分析了稀土分离提取发展方向,重点讨论了稀土元素的微生物回收方法和发展趋势。微生物表面大量的疏水性官能团和亲水性官能团,通过物理附着,或与金属离子以离子键、配位键等化学键与稀土离子结合,富集分离稀土金属。Rare earth elements have been paid attention to because of their unique properties and application in industry. The characteristics and resource distribution of rare earth elements were introduced. The Metallurgical status and process system of rare earth metal were expounded,the development direction of rare earth separation and extraction was analyzed. The microbial recovery methods and development trend of rare earth elements were emphatically discussed.Rare earth ions can be enriched and separated by physical attachment or ionic bonds,coordination bonds and other chemical bonds between earth ions and microorganism because there were a large number of hydrophobic functional groups and hydrophilic functional groups on the surface of microorganism.
