摘要
小秦岭金矿带是我国重要的岩金矿区之一,区域内金矿分布广泛。利用多种分析测试手段对矿石的化学成分、矿物组成、自然金粒度以及矿石的结构构造等进行了详细研究。该矿石为石英脉型多金属金矿石。共见自然金44粒。在嵌布关系上,以黄铁矿裂隙金为主,与晚结晶的方铅矿、黄铜矿伴生。自然金形态以粒状和板状为主。详细的工艺矿物学研究为小秦岭金矿的选矿工艺和开发提供了理论数据。
The Xiao Qinling gold ore belt is one of the most important areas of gold deposits in China, gold de- posits are widespread in the area. The features of process mineralogy of the ore, including the chemical composi- tion, 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. Totally 44 gold grains were found in the study. Re- garding the dissemination characteristics,the type of pyrite fissure gold is the main type, it is associated with late- crystallized galena and chalcopyrite. The morphology of native gold is mainly granular and plate. The study pro- vides theoretic basis for the choice of mineral processing technique and exploitation for the gold ore in Xiao Qinling area.
