中文摘要：

南京栖霞山铅锌银矿随着开采深度不断加深,矿石性质发生了较大变化。为此,通过工艺矿物学研究,查明了深部矿石的化学成分及矿物组成、结构构造、主要矿物的嵌布特性、主要矿物的工艺特征及赋存状态,从而为矿山进行选矿工艺改造以适应矿石性质的变化提供了依据。

英文摘要：

With the mining depth getting deeper in Qixiashan lead-zinc-silver mine area,its major ore properties are changing.To this end,the process mineralogy studies are carried out to identify its chemical composition,mineral composition,texture and structure,the embedded characteristics of main minerals,the process characteristics and occurrence of major minerals,so as to provide a basis for the beneficiation process reform of the mine to adapt to the ores＇ nature.
