为查明西矿矿石中铌、稀土元素的存在形式,铌、稀土元素的赋存矿物,我们采用了铌、稀土的物相分析、岩矿鉴定、电子探针分析、扫描电镜微区分析与数字图象处理综合技术等方法进行对比。查明铌主要以铌钽酸盐矿物形式存在;稀土主要以稀土磷酸盐、稀土氟碳酸盐矿物形式存在。对已经发现的27种单矿物内稀土的含量作了对比研究,建立了铌矿物和稀土矿物的矿物系
In order to find out the existing forms of niobium and rare earth elements, niobium and rare earth elements in the ore of West Mine, we used the phase analysis of niobium and rare earth, rock identification, electron probe analysis, SEM Digital image processing technology and other methods of comparison. It is found that niobium exists mainly in the form of niobate and tantalate minerals. Rare earths mainly exist as rare earth phosphates and rare earth fluorocarbon minerals. The contents of rare earths in 27 kinds of single minerals that have been found are compared and the mineralogy of niobium and rare earth minerals is established
