| 摘 要： | 主要进行了X荧光对Th的预富集试验研究。对使用X荧光拣选机富集到的富钍矿石经过XRD、手持X-ray进行分析,确定了X荧光识别钍的准确性,并得到了钍元素一般赋存于稀土矿物中,如氟碳铈矿、独居石,并发现使用X荧光可以富集钍的独立矿物"铁钍石"。之后使用能量色散X射线荧光矿石分选机拣选,阈值为0.3时拣选出的含钍矿物的品位提高到2.34倍,钍的回收率达到18%,并确定了阈值与品位的对应关系,确定阈值为0.4时分选效果最好。这不仅直接降低了进入选冶流程中矿石的放射性,还为钍的提纯提供了预富集技术。

| Abstract: | This paper mainly studies the pre-enrichment experiment of X-fluorescence to Th. The rich thorium ore enriched by X-fluorescent pickers was analyzed by XRD, scanning electron mirrors and hand-held X-ray for process mineralogy, and the accuracy of X-fluorescent identification of thorium was determined, and the radon elements were generally deposited in rare earth minerals, such as fluorocarbon palladium, living alone, and found that x-fluorescent can be enriched with the independent mineral "iron thorium". Then the use of energy dispersion X-ray fluorescent ore sorter selection, the threshold of 0.3 picked the grade of radon-containing minerals increased by 2.34 times, the recovery rate of radon reached 18%, and determined the correspondence between the threshold and grade, to determine the threshold of 0.4 time selection effect is the best. This not only directly reduces the radioactivity of the ore entering the selection process, but also provides pre-enrichment technology for the purification of radon. |
