利用电子探针查明铅精矿中银的存在形式

Research on the Speciation of Silver in Lead Concentrates by Electron Probe Microanalysis

摘要: 利用光学显微镜、电子探针对铅精矿中银的赋存状态进行了分析。结果表明，此批铅精矿舍有大量的非天然银矿物，银颗粒呈疏松絮状物分布在方铅矿周围。

Abstract: The speciation of silver in the lead concentrates were analyzed by means of optical microscope and electron probe microanalyser (EPMA).The results indicated that large amounts of non-natural silver grains existed in this branch of lead concentrates and th
