摘　　要：采用电子探针（EPMA）及矿物自动分析仪（MLA）对邹家山铀矿石中稀土赋存特征的研究表明,稀土赋存状态主要为类质同象分散相,少量独立矿物相及部分离子吸附相。其中：稀土类质同象分散相赋存于铀矿物、磷灰石等矿物;稀土独立矿物相几乎全是赋存于磷钇矿,少量独居石。磷钇矿以细小颗粒为主,与铀矿物、磷灰石、绢云母等共伴生;稀土离子吸附相是赋存于粘土矿物等。此成果可为回收稀土资源及探索成因提供依据。Based on the study for the occurrence characteristics of REE in Zoujiashan uranium ore by using the electron probe microanalyzer（ EMPA） and the mineral liberation analyser（ MLA）,several important results are achieved and listed as follow：（ 1） The dispersed phase of REE that is as isomorphism hosts in the uranium ore and apatite,etc;（ 2） Most of the independent REE minerals are xenotime,and only small amount of monazite are found in the uranium ore. The main size of xenotime particles is small,which associated with the uranium ore,apatite and sericite;（ 3） The adsorption phase of REE ions mainly hosts in clay minerals. These results will provide some evidences for the recycling of REE resources and exploring the contributing factors.
