| 摘 要： | 山东某海关检验监管过程中抽检一批黄金矿砂，要求鉴别其产品属性，杜绝不法供应商将掺杂冶炼渣的金矿砂运输至我国。因此，本文将X射线荧光与衍射分析技术方法联合应用于矿物分析，根据已知元素种类和物相结构，并综合不同状态下样品外观、物理和化学等特性，得出产品具有天然矿石的特性，属于天然产黄金矿砂，其金含量为51.3 g/t，银含量为815.5 g/t，主要物相有石英、闪锌矿、方铅矿和黄铜矿等。这种检验黄金矿砂的一般鉴别程序和方法，为海关检验监管进口黄金矿砂提供了技术支撑和科学依据，避免了不法供应商以黄金矿砂名义进口其他产品的逃税及走私固体废物现象发生，进而维护了国家利益和环境安全。

| Abstract: | Added value tax in import and customs duty are free for gold ore.One block of “gold ore” was checked by one Custom to identify its property.This paper demonstrates the product belongs to gold ore by X ray fluorescence and diffraction analysis and comprehensive analysis of appearance，physicochemical characteristics in its different state，which has natural characteristics and with gold content of 51.3 g/t，silver 815.5 g/t.The phases is dominated by quartz，sphalerite，galena，chalcopyrite etc.One identification program and method for gold ore is formed in order to offer scientific basis to Custom’s inspection. |
