| Abstract: |
| The xiao Qinling gold ore belt is one of the most important gold ore deposits in China, the gold deposits are widespread in the area. The features of process mineralogy of the ore, including the chemical composition, mineral composition, particle size of gold, and the structure of ore is studied in detail by various means in the paper．The ore belongs to quartz vein type polymetallic gold ore. 44 gold grains were found in the study. In dissemination characteristics,the type of pyrite fissure gold is the main type, it is associated with late crystallization galena and chalcopyrite. The morphology of native gold is mainly granular and plate. The study provides theoretic basis for the choice of mineral processing technique and exploitation for the gold ore in xiao Qinling area. |
