围绕取样代表性和试样加工均匀性等问题,研究了粗铜和粗铅中金银分析试样加工粒度对金银品位的影响,产品锭内金银分布及规律,产品锭与小锭金银分布一致性及产品锭小样锭表层金银分布规律。通过在9个企业取制上千个试样,分析处理万余个数据和认真研究,为制定粗铜粗铅中金银分析取制样方法提供了科学依据,并纳入粗铜粗铅技术标准。
Focusing on the sampling representativeness and sample processing uniformity, the effects of the processing grain size of gold and silver analysis sample on the grade of gold and silver, the distribution of gold and silver in the product ingot and the rules of product ingot and small ingot gold Silver distribution consistency and product ingot ingot gold and silver distribution rules. By taking thousands of samples from nine enterprises, analyzing and processing more than 10,000 data and earnestly studying them, it provides a scientific basis for making sample preparation methods for gold and silver analysis in crude copper, and incorporates the standard for crude lead .
