摘　　要：针对广东某复杂难选金矿石进行了工艺矿物学研究。结果表明:该含金矿石中主要有价元素为金和银,还具有含碳、高砷、含泥量大的特性。原矿中金除了与黄铁矿等硫化物密切共生外,还有部分嵌布于石英等脉石矿物中,赋存状态复杂;矿石中金及载体矿物嵌布粒度均很细,属典型的难选难浸金矿石。结合工艺矿物学研究结果,本文还提出了该矿石开发利用的建议。The technological mineralogy of a complex refractory gold ore in Guangdong was studied.The results show that the main valuable elements in the gold-bearing rocks are gold and silver,and have the properties of carbon,arsenic and mud.In the raw ore,gold is closely associated with sulfide minerals such as pyrite,and some of it is embedded in quartz and other gangue minerals.The microstructure of gold and carrier minerals in ore is very fine.Combined with the research results of technological mineralogy,some suggestions for exploitation and utilization of the ore are also proposed in this paper.
