  • 高品位矿石金标准物质的研制与应用……刘 妹,顾铁新,鄢卫东
  • 摘 要:目前,中国已研制的国家一级矿石金成分分析标准物质有5个,金最高品位不足60μg/g,缺乏更高品级的质量监控标准。中国地质科学院地球物理地球化学勘查研究所研制了1个金品位为92μg/g的矿石金(硫化物金精矿)成分分析标准物质。该标准物质于20073月经国家质量监督检验检疫总局审批为国家一级标准物质(编号为GBW07810)。该标准物质经百余家实验室近10年的应用检验,量值准确可靠,为金矿勘查、开发、选冶及精矿产品商检中金的测试提供了基础标准和技术支持,增强了中国金精矿国际贸易检测与仲裁的话语权。

    Preparation and application of geochemical reference material for sulfide gold concentrate……Liu Mei,Gu Tiexin,Yan Weidong

    AbstractThere are 5 national reference materials developed for composition analysis of gold concentrates in China.However,there is no higher grade standard for quality control,for the highest gold grade of them is below 60 μg/g.To meet this demand,one gold reference material of sulfide concentrate whose grade can reach 92.0 μg/g was developed by the Institute of  Geophysical and Geochemical Exploration(IGGE).And it was approved to be National Reference Material(SeriesNo.GBW 07810 ) by General Administration of Quality Supervision,Inspection and Quarantine of the People's Republic of China(AQSIQ) in March 2007.This materialcan supplement the series of gold concentrate reference materials and serve the analytical quality control of gold exploration,mining,beneficiation,metallurgy and commodity inspection.Also it would promote China’s authority in the inspection and arbitration of gold concentrates in international trade.

    Keywords:gold concentrate; reference material; uncertainty; development; application
