【摘要】：老挝班康姆某矿床位于老挝沙耶武里省巴莱县西南部,属于琅勃拉邦—黎府成矿带。前人已完成矿床铜、金资源量的预测,尚未对矿石工艺特性进行研究。本文利用化学分析、光学显微鉴定、X射线扫面电镜能谱分析、物相分析等方法,对该矿床铜金矿石的工艺特性进行了系统研究。研究确定矿石属原生硫化物型铜(伴生金)矿石,可选性好。选矿回收的目标元素为Cu、Au,品位分别为0.74%、0.94g/t。Cu主要以黄铜矿形式存在;Au主要以银金矿形式存在,以包裹金为主。黄铜矿为回收Cu、Au的目标矿物。当磨矿细度为-0.074mm占70%±之时,选矿试验得到Cu回收率90.8%、Au回收率63.5%,铜精矿产品达到国家二级标准。以上结果表明,矿石工艺矿物学研究对选矿试验具有良好的指导作用。
[Abstract]:A deposit in Bankom, Laos, is located in the southwest of Pallay County, Shayevuri Province, Laos. It belongs to the Luangburg-Lifucheng metallogenic belt. The prediction of copper and gold resources of the deposit has been completed by predecessors, but the ore technological characteristics have not been studied in this paper by means of chemical analysis. By means of X-ray scanning electron microscope (SEM) energy dispersive analysis and phase analysis, the technological characteristics of copper and gold ore in this deposit are systematically studied. It is determined that the ore belongs to primary sulfide type copper (associated gold) ore. The target element for ore dressing and recovery is Cu au, the grade of 0.74 g / t Cu is 0.74 g / t.Cu mainly exists in the form of chalcopyrite, mainly in the form of silver gold deposit and mainly in the form of wrapped gold. Chalcopyrite is the target mineral for recovery of Cuo au. When the grinding fineness is -0.074 mm, 70% 卤. The copper recovery rate of 90.8% and 63.5% of au was obtained from the ore dressing test, and the copper concentrate product reached the national second class standard. The above results show that the mineralogical study of ore processing has a good guiding effect on the ore dressing test.
