摘　　要：某铜铅锌矿床矿石中伴生银主要以硫化物及碲化物形式存在,主要银矿物为银锑黝铜矿、碲银矿、辉银矿,银的主要载体矿物为黄铁矿、方铅矿、闪锌矿和黄铜矿。除银锑黝铜矿外,银矿物粒度细小,一般小于0.01mm。针对该矿石性质,选择合适的磨矿细度,使黄铁矿、闪锌矿及脉石矿物中的银锑黝铜矿得以充分解离,并使之进入铜精矿或铅精矿,以及充分回收方铅矿是提高伴生银回收率的主要途径。The associated silver in a deposit is mainly occurred in the form of sulphides and tellurides, and the silver - .stibium panabase , hessite , argentite are major silver minerals. The main carrier minerals of silver are pyrite ,galenite, sphalerite and chalcopyrite. Except silver - stibium panabase,the grain size of silver minerals is less than 0.01mm. It is very important for us to choose rational grinding fineness and sufficiently recover galenite for increasing recovery rate of associated silver.
