摘　　要：这是一篇矿物加工工程领域的论文。某含砷高硫金矿中金矿物与黄铁矿、毒砂共生关系密切,在实际生产过程中精矿金回收率不理想。为提高精矿金回收率,同时兼顾精矿金品位,针对该矿物特点,通过系统条件实验、浮选时间实验和精选实验得到了浮选工艺参数和流程,继而开展开路实验和闭路实验,获得了较好的浮选指标。为进一步提升浮选指标,对浮选中矿进行再磨再浮实验,并对中矿再磨浮选尾矿进行氰化浸出实验,最终得到金选冶总回收率91.94%的满意指标。This is an article in the field of mineral processing engineering.The gold mineral in an arsenic bearing high sulfur gold mine has a close symbiotic relationship with pyrite and arsenopyrite,and the recovery rate of concentrate gold is not ideal in the actual production process.In order to improve the recovery rate of concentrate gold and take into account the grade of concentrate gold,according to the characteristics of this mineral,the flotation process parameters and process are obtained through system condition test,flotation time test and beneficiation test,and then the open circuit test and closed circuit test are carried out to obtain better flotation indexes.In order to further improve the flotation index,the regrinding and flotation test of flotation middling is carried out,and the cyanide leaching test of middling regrinding flotation tailings is carried out.Finally,the satisfactory index of 91.94%of the total recovery of gold dressing and metallurgy is obtained.
