摘要
采用扫描电子显微镜、光学偏光显微镜、化学分析、能谱分析、MLA矿物自动检测分析等手段对含碲金矿石中的金-银碲化物的化学成分、共生组合、赋存状态进行系统普查。结果表明,金-银碲化物是该金矿中最重要的一类金矿物,发现除自然金外,还含有亮碲金矿、含银碲金矿、杂碲金银矿等碲金矿。金矿物颗粒细微,多数粒度小于5μm,它们主要嵌布于黄铁矿、脉石、磁铁矿的表面、裂隙和孔洞中。该矿物中主要金属硫化物为黄铁矿,主要脉石矿物为石英和方解石,属于高钙镁微细粒Te-Au型复杂难处理金矿石。研究结果对此类矿石分选工艺流程的制定具有指导意义,可为该类难处理金矿的开发利用提供借鉴。
This study uses scanning electron microscopy, optical polarized light microscope, chemical analysis, element analysis, energy spectrum analysis, MLA mineral automatic detection and analysis technology and other methods to analyze the chemical composition, symbiotic combination, and excipients of gold-silver telluride in tellurium-containing gold ore.System census of the status of storage.The results show that gold-silver telluride is the most important type of gold minerals in this gold deposit.In addition to natural gold, it has also been found that there are bright tellurium gold deposits, silver-bearing tellurium gold deposits, and mixed tellurium gold and silver deposits.Gold minerals have fine particles, most of which are smaller than 5 μm.They are mainly embedded in the surface, cracks and holes of pyrite, gangue and magnetite.The main metal sulfide of this mineral is pyrite, and the main gangue minerals are quartz and calcite.It belongs to the high-calcium-magnesium fine-grained Te-Au type complex refractory gold ore.The research results have guiding significance for the formulation of this type of ore separation process, and can provide a reference for the development and utilization of this type of refractory gold ore.
