摘　　要：围绕取样代表性和样品加工均匀性等问题,研究了铅铋合金锭中金银分析试样加工粒度对金银品位的影响,锭内金银分布及规律。通过对铅铋合金锭中金、银分布情况的研究结果,制定了铅铋合金锭的采样、样品加工及化验分析方案。Focusing on the sampling representative and the uniformity of sample processing,the influence of processing grain size of gold and silver in the lead-bismuth alloy on the gold and silver grade,and the distribution and regularity of gold and silver in the product ingot were studied.The sampling,sample processing and laboratory analysis schemes of lead-bismuth alloys were developed by testing the distribution of gold and silver in lead-bismuth alloys.
