1.1 本试验方法用于测定含量在0.2μg/g至17μg/g范围内的铜精矿中的金 微克/克。 注1: 范围下限是根据实践设定的 E1601 . 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关特定警告声明，请参阅 11.3.1 , 11.5.4 和 11.6.5 . 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 在采矿业使用的冶金过程中，在浮选-浓缩过程中，金通常与铜一起携带。这类材料的冶金核算、过程控制和精矿评估程序取决于铜精矿中金的准确测量。 本试验方法旨在成为冶金实验室的参考方法和解决商业交易纠纷的仲裁方法。它也是一种确定的方法，旨在测试材料是否符合成分规范，并为标准物质的认证提供数据。至关重要的是，通过将该方法应用于适当的参考材料，同时以与应用于未知量相同的方式验证该方法的每个性能。 5.2 假设所有使用该测试方法的人都是经过培训的分析员，能够熟练且安全地执行测试。预计工作将在适当的质量控制实践（如指南中所述）下，在配备适当的实验室中进行 E882 .

1.1 This test method is for the determination of gold in copper concentrates in the content range from 0.2 μg/g to 17 μg/g. Note 1: The lower scope limit is set in accordance with Practice E1601 . 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 11.3.1 , 11.5.4 , and 11.6.5 . 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 In the metallurgical process used in the mining industries, gold is often carried along with copper during the flotation concentration process. Metallurgical accounting, process control, and concentrate evaluation procedures for this type of material depend on an accurate, precise measurement of the gold in the copper concentrate. This test method is intended to be a reference method for metallurgical laboratories and a referee method to settle disputes in commercial transactions. It is also a definitive method intended to test materials for compliance with compositional specifications and to provide data for certification of reference materials. It is essential that each performance of the method be validated by applying it to appropriate reference materials at the same time and in the same manner as it is applied to the unknowns. 5.2 It is assumed that all who use this test method will be trained analysts capable of performing skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E882 .
