The Qingshankou Formation is one of the primary ore-bearing layers for uranium deposits in the Songliao Basin, where the techno-metallurgical characteristics of the ores directly determine the feasibility of in-situ leaching uranium. This study focuses on sandstone type ores in the Qingshankou Formation, employing petrographic analysis, scanning electron microscopy, energy-dispersive spectroscopy, and electron probe microanalysis to conduct techno-metallurgical research, systematically revealing the occurrence patterns of uranium minerals. The results indicate that uranium minerals in fine sandstones of the Qingshankou Formation are predominantly uraninite and pitchblende, primarily distributed along the edges of clastic particles, which facilitates contact between uranium minerals and leaching solutions. Additionally, the pores in fine sandstones are mainly intergranular, promoting uniform diffusion of leaching agents. In contrast, uranium minerals in mud breccia are primarily uraninite, mainly distributed within the mud breccia, which hinders contact between leaching solutions and uranium minerals, increasing leaching difficulty. The study suggests that the Qingshankou Formation of a uranium deposit in the Songliao Basin has the potential to become an ideal mining horizon in the region.

青山口组作为松辽盆地内铀矿床的主要发育层位之一,其矿石的工艺矿物学特征直接制约地浸开采的可行性。本研究聚焦于青山口组砂岩型矿石,采用岩矿鉴定、扫描电镜观察、能谱及电子探针分析等手段,开展了工艺矿物学研究,系统揭示了铀矿物的赋存规律。结果表明:青山口组细砂岩中的铀矿物以铀石和沥青铀矿为主,主要分布在碎屑颗粒的边缘,有利于铀矿物与浸出液接触发生反应;且细砂岩中的孔隙以粒间孔为主,有利于浸出剂均匀扩散。而泥砾岩中的铀矿物以铀石为主,且主要赋存于泥砾内部,不利于浸出液与铀矿物接触,增加了浸出难度。研究表明,松辽盆地某铀矿床青山口组有望成为该地区较为理想的开采层位。

青山口组作为松辽盆地内铀矿床的主要发育层位之一,其矿石的工艺矿物学特征直接制约地浸开采的可行性。本研究聚焦于青山口组砂岩型矿石,采用岩矿鉴定、扫描电镜观察、能谱及电子探针分析等手段,开展了工艺矿物学研究,系统揭示了铀矿物的赋存规律。结果表明:青山口组细砂岩中的铀矿物以铀石和沥青铀矿为主,主要分布在碎屑颗粒的边缘,有利于铀矿物与浸出液接触发生反应;且细砂岩中的孔隙以粒间孔为主,有利于浸出剂均匀扩散。而泥砾岩中的铀矿物以铀石为主,且主要赋存于泥砾内部,不利于浸出液与铀矿物接触,增加了浸出难度。研究表明,松辽盆地某铀矿床青山口组有望成为该地区较为理想的开采层位。

The Qingshankou Formation is one of the primary ore-bearing layers for uranium deposits in the Songliao Basin, where the techno-metallurgical characteristics of the ores directly determine the feasibility of in-situ leaching uranium. This study focuses on sandstone type ores in the Qingshankou Formation, employing petrographic analysis, scanning electron microscopy, energy-dispersive spectroscopy, and electron probe microanalysis to conduct techno-metallurgical research, systematically revealing the occurrence patterns of uranium minerals. The results indicate that uranium minerals in fine sandstones of the Qingshankou Formation are predominantly uraninite and pitchblende, primarily distributed along the edges of clastic particles, which facilitates contact between uranium minerals and leaching solutions. Additionally, the pores in fine sandstones are mainly intergranular, promoting uniform diffusion of leaching agents. In contrast, uranium minerals in mud breccia are primarily uraninite, mainly distributed within the mud breccia, which hinders contact between leaching solutions and uranium minerals, increasing leaching difficulty. The study suggests that the Qingshankou Formation of a uranium deposit in the Songliao Basin has the potential to become an ideal mining horizon in the region.
