摘　　要：采用矿相学、电子探针、化学物相等方法，查明会泽七0厂铅锌矿矿石中的银主要以独立矿物的形式产出，方铅矿为银的主要载体矿物。表生条件下的次生变化使氧化矿石中的银趋于分散。築ased on the mineragraphy， electronmicroscopic probing and chemical phase analysis，it is proposed that the silver of oresoccurs as independent minerals，and galena serves as the main silver - carrier. The secondary changes result in dispersion of silver in oxideores. The secondary enriching of silver occurs in depth.
