内蒙古黑鹰山铁矿区含重稀土磷灰石矿点中钇的赋存状态

Occurrence of yttrium in heavy-RE-containing apatite mine dot of Heyingshan iron mine area in Inner Mongolia

黑鹰山磷灰石矿点位于黑鹰山铁矿区Ⅱ～Ⅲ矿段中间,是前人在1∶5万区调中发现的矿点,并且做了简单的评价工作。主要进行了探槽工程揭露,并取了样品,以此来控制矿体形态及大小,并估算了储量,在样品分析结果中发现稀土元素铈、镧、钇含量较高,特别是钇,光谱及组合样分析结果显示均大于边界品位要求。通过大量资料、数据分析来推测钇的赋存状态,旨在提出在利用磷矿石时要注意稀土元素回收利用问题,进而提高矿床的经济价值。

Heiyingshan apatite mine dot is located in the middle of the II-III ore section of the Heiyingshan i ron deposit.It was discovered by regional geologic survey in the 1∶50,000,and a simple evaluation work was made.The exploration project was carried out and samples were taken to control the shape and size of the ore body and to estimate the reserves.The results of sample analysis found that the rare earth elements helium,lanthanum,and yttrium were higher,especially yttrium.The results of spectral and composite sample analysis showed that the boundary grade requirement is higher than that of the boundary grade.In this study,occurrence state of yttrium was estimated with a lot of data and data analysis,so as to raise the economic value of the ore deposit.
