青海什多龙银铅锌矿床银的赋存状态研究

The Study of Qinghai Shiduolong Ag-Pb-Zn Mineral

文章对什多龙银铅锌矿床的矿石特征、银的赋存状态等进行了分析研究,结果表明,该矿床的矿物组成较简单,矿石矿物主要由方铅矿、闪锌矿、透辉石或石英组成,占95%以上。各类矿石矿物中均不同程度的含银,其中方铅矿是主要载银矿物,银以类质同象和硫化银包裹状态赋存于方铅矿中,占88.4%,银品位与铅品位呈正相关关系。

The paper has studied the features of shiduolong Ag - Pb - Zn deposit and the occurrence of Ag. The resuits show that the composition of the mineral deposits is simple and ore minerals are mainly made from the galenam, sphalerite, diopside and quartz, which account for more than 95 %. Different levels of silver is contained in both types of ore, which is mainly in the galena. Silver in the same category as the quality and Galena silver sulfide inclusions occur in the state that accounts for 88.4%. Thore is a positive correlation between the Pb - Ag - grade.
