Resumen
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
