会泽铅锌矿深部矿体稀贵金属的赋存状态

对会泽铅锌矿深部矿体稀贵金属的赋存状态进行了研究。结果表明,矿石中铅锌品位比较高,伴生元素锗、镉和银也已达到综合利用指标要求。锗和镉主要以类质同象存在于闪锌矿中,银主要以独立矿物形式存在于方铅矿中。在选别时,锗和镉进入锌精矿,而银进入铅精矿,锗、镉和银的回收率随铅锌回收率的增加而增加。因此,矿石中锗、镉和银亦可综合回收,该矿床具有良好的经济价值。

OCCURRENCE STATE OF RARE DISPERSED AND PRECIOUS METALS IN DEEP OREBODY AT HUIZE LEAD & ZINC MINE

This paper studies the occurrence state of rare dispersed and precious metals in deep orebody at Huize lead & zinc mineThe results indicate that the grades of Pb and Zn in ore are higher,and the contents of accompanying elements Ge,Cd and Ag in ore come up to the standards for comprehensive utilization of valuable elements in Pb-Zn depositGe and Cd exist mainly in sphalerite as isomorphic impurities while Ag exists mainly in galena as independent minerals of AgAt the time of beneficiation,Ge and Cd go into zinc concentrate while Ag goes into lead concentrateThe recoveries of Ge,Cd and Ag will increase with increased recoveries of Pb and ZnThus,Ge,Cd and Ag in ore are possible to be recovered comprehensivelyThis deposit will produce a good economic benefit
