Abstract

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
