摘　　要：介绍串级萃取理论在选矿中的应用,阐述了串级萃取与串级选矿之间的理论关系,归纳了如何应用于串级选矿的基本理论、实验方法和实验结果。在选矿工艺中应用该理论能同时得到高纯度和高回收率的产品,稀土回收率达到90%,品位为60%,通过理论计算可以得到选矿工艺技术条件,达到预期的技术指标,对综合利用复合矿资源的选矿工艺技术具有重要意义。Applicatin of the stage-connect solvent extaction theory for the mineral processing is introduced in the article.. The writer has introduced the basic theory, experiment method and text target in the article. Applying the theory may raised technology target largyly,and get both high purity and high rate of recovery. The theory has an important characteristic which can make good technology condition from calculating and get a desirable target, so it has important significance for processing complex resources.
