| 摘 要： | 云南某铅锌矿中主要的回收对象为闪锌矿和方铅矿,其锌、铅品位分别为5.64%和0.92%。通过系统的工艺矿物学研究,全面地了解了该铅锌矿的矿石性质。结果表明:该矿石的氧化程度较高并且矿石中闪锌矿和方铅矿的嵌布粒度细,这是影响其选矿指标的最主要的因素。

| Abstract: | Sphalerite and galena are the primary recoverable minerals in a lead-zinc ore in Yunnan.The grade of zinc and lead are 5.64% and 0.92% respectively.Through systemic process mineralogy study,it is found that the oxidation degree of the ore is high and the grain size distribution of sphalerite and galena are all fine.The results show that these two reasons are the main factors influencing floatation indexes of the ore. |
