- Abstract
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 p.m. 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.
