Copper and zinc sulfide concentrates - Determination of silver content - Acid digestion and flame atomic absorption spectrometric or inductively coupled plasma optical emission spectrometric method
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
