标准摘要
[中文适用范围]： 本文件规定了酸性消解和火焰原子吸收光谱法（AAS）或电感耦合等离子体发射光谱法（ICP-OES）测定铜和锌硫化精矿中银质量分数的方法。 该方法适用于银含量在以下范围内的精矿： 铜精矿：10 g/t 至 800 g/t 锌精矿：10 g/t 至 800 g/t [外文原描述]： This document specifies an acid digestion and flame atomic absorption spectrometric (AAS) method, or inductively coupled plasma optical emission spectrometric (ICP-OES) method for the determination of the mass fraction of silver in copper and zinc sulfide concentrates. The method is applicable to concentrates having silver contents in the following ranges. — copper concentrates: 10 g/t to 800 g/t ; — zinc concentrates: 10 g/t to 800 g/t
