岩石矿物标准参考样品是化学成分均匀、含量稳定,并具有足够细度的,有代表性的基准物质。在地质、冶金、化工部门的科研生产中,它既可保证分析质量,又可统一量值,并保证量值的准确传递,同时在实现岩石矿物分析手段现代化、仪器化、加强国内外情报技术交流等方面起着重要作用。近来,随着国际货币和工业发展对黄金需求量的增加,我国地质事业出现了一个黄金普查、找矿的热潮;随着低品位金矿选冶新方法在工业实践中不断应用,黄金矿床的边界品位
Rock mineral reference sample is a chemical composition of uniform, stable content, and has a fine enough representative reference material. In the scientific research and production of geology, metallurgy and chemical industry departments, it can guarantee the quality of analysis as well as unify the values and ensure the accurate delivery of the values. At the same time, it is necessary to modernize and instrumentalize the analysis of rock and mineral resources and strengthen the domestic and foreign intelligence technology Exchange and other aspects play an important role. Recently, with the increasing demand for gold from the international monetary and industrial development, a gold census and a prospecting craze have emerged in the geological undertakings in our country. With the continuous application of low-grade gold ore dressing and smelting methods in industrial practice, the gold deposits Border grade
