摘　　要：采用多元素分析、场发射扫描电镜、X射线能谱仪及AMICS自动矿物分析系统对白云鄂博矿床主、东矿内萤石型铁矿石中的稀土元素分布规律进行了系统地分析,发现稀土含量与稀土配分均存在一定的差异,并提出了精细化生产建议,指出La,Ce,Pr,Nd,Sm,Eu的最佳矿物原料分别为东矿氟碳铈矿、主(东)矿氟碳铈矿、主矿氟碳铈矿(独居石)、主矿独居石、东矿独居石、主(东)矿独居石。该研究对进一步认识白云鄂博矿床稀土资源和综合高效利用这一资源具有一定的指导意义。The distribution regularity of rare earth in fluorite type iron of main ore and east ore in Bayan Obo was systematically studied,and via the multi element analysis,SEM-EDS and the automatic mineral analysis system,some differences in the content and the distribution of the rare earth between main ore and east ore were found,and the suggestion of fine production was put forward. The best mineral raw materials of lanthanum,cerium,praseodymium,neodymium,samarium and europium is the east ore bastnasite,main（ east） ore bastnaesite,main ore bastnasite and monazite,the main ore monazite,east ore monazite,the main（ east） ore monazite respectively.This study has a certain guiding significance for the further understanding the rare earth resources and the comprehensively utilizing of the resources of Bayan Obo deposit.
