本文主要是叙述一种分析铅矿中微量元素的半定量光谱照相方法,并通过总结主要由方铅矿组成129个硫化物精矿的分析结果来证明它的实用意义。样品堆放了好几年的时间,多数是为了其它目的例如同位素铅分析所收集的,或者是回收金时精选样品的副
This paper describes a semi-quantitative spectrophotometric method for the analysis of trace elements in lead ore and demonstrates its practical significance by summarizing the results of the analysis of 129 sulfide concentrates mainly composed of galena. Samples have been deposited for several years, mostly for other purposes such as collected by isotope lead analysis or vice versa
