铜铅锌(银)矿石与精矿标准物质的研制

制备铜铅锌(银)矿石与精矿标准物质。该多金属矿系列标准物质由4个不同品位的铜、铅、锌(银)矿石及铜、铅、锌3个精矿共7个样品组成,12个单位协作分析定值,定值元素包括矿石主成分Cu ,Pb ,Zn ,Ag ,Fe ,S和可综合利用的稀有分散元素Cd ,Ga ,Ge ,In ,Tl,Se及伴生微量元素与脉石成分计2 6种。由国家质量监督检验检疫总局批准为国家一级标准物质。该标准物质可广泛用于铜铅锌银及多金属矿的矿产勘查、开发、选冶和商检成分测试的量值标准与分析质量监控

Certified Reference Materials Preparation of Copper,Lead and Zinc (Silver) Ores and Concentrates

The certified reference materials of copper, lead and zinc (silver) are prepared. This series of certified reference materials consist of seven polymetallic materials, including four ores of copper, lead and zinc (silver) with various grades and three concentrates of copper, lead and zinc. These samples are analyzed by twelve institutes and laboratories. Certified values of twenty-six elements and components are assigned and their certified values include major valuable elements, Cu, Pb, Zn, Ag, Fe and S, comprehensive utilizable rare disseminated elements, Cd, Ga, Ge, In, Tl and Se, minor and associated trace elements and major gangue components. The certified reference materials are approved as the national primary reference materials by State General Administration of Quality Supervision and Inspection and Quarantine, then could be used for chemical analysis as calibration samples and monitoring the quality of measurement in geochemical exploration, mining development, mineral separation and commodity inspection of copper, lead, zinc, silver and polymetallic ores.
