摘要
邹家山铀矿床是相山矿田中品位最高、规模最大的矿床,伴生大量稀土和钼等有用组分。探讨分析邹家山铀矿床中U、HREE、LREE、Mo特征以及它们之间的相互关系,可为选冶和成矿研究提供一些参考。采用野外地质调查、化学分析、电镜分析和浸出活化实验等方法研究,结果表明,邹家山铀矿床富含U-HREEMo,且相互之间高度正相关,在矿石富集倍数高、可达百上千倍;LREE在矿石中有所富集,但富集倍数不高、多不超过3倍;U-HREE相关性明显高于U-LREE的相关性;在酸性氧化环境中U-HREE-Mo与LREE更易进入热液中,其中HREE活化浸出率是LREE的2倍左右。
The Zoujiashan uranium deposit is the largest and highest-grade deposit within the Xiangshan ore field,containing significant amounts of associated rare earth elements(REEs)and molybdenum(Mo).This study analyzes the characteristics of U,HREE,LREE and Mo in the uranium deposit,as well as their interrelationships,to provide insights for mineral processing and metallurgical research.Using field geological surveys,chemical analysis,electron microscopy,and leaching activation experiments,the results indicate that the Zoujiashan uranium deposit is rich in U-HREE-Mo,and they exhibit a strong positive correlation.The enrichment factor of these elements in the ore can reach hundreds to thousands of times.Although LREEs are also enriched in the ore,their enrichment factors are relatively low,generally not more than 3 times.The correlation between U-HREE and U-LREE is significantly higher than that of U-LREE.In the acidic oxidizing environment,U-HREE-Mo and LREE are more likely to be entered into the hydrothermal fluid,with HREEs exhibiting nearly twice the leaching activation rate of LREEs.
