摘要
采用矿物解离度分析仪(MLA)分析、电子探针分析等方法对华阳川铀多金属矿进行了详细的赋存状态研究。分析结果显示矿石中90.99%的铀和84.94%的铌赋存在铌钛铀矿中,46.15%的铅赋存在方铅矿中,92.55%的稀土赋存在褐帘石中,锶和钡分布较分散。铌钛铀矿和方铅矿等有用矿物粒度较粗有利于其选矿富集。褐帘石中稀土元素含量低、提取难度较大,综合利用较为困难。锶和钡含量低、分布分散,综合利用价值不大。
The MLA,EPMA,and other analysis was used to study the occurrence of the useful minerals in Huayangchang uranium polymetallic ore in this paper.The result shows that 90.99%of uranium and 84.94%of niobium in the ore exists in betafite.46.15%of lead exists in galena.And 92.55%of rare earth elements exist in allanite.Strontium and barium in the ore exist in various minerals.The particle size of the betafite and galena are very crude,which are beneficial to be separated.The content of rare earth elements in allanite is so low that it is difficult to be extracted.So the rare earth elements in the ore can’t be used.As the content of strontium and barium is low,and it exist dispersion,so it can’t be used.
