This International Standard specifies an acid decomposition, solvent extraction, flame atomic absorption spectrometric procedure for the determination of gold in zinc sulfide concentrates.
The method is applicable to the determination of gold in zinc concentrates containing up to 60 % (m/m) zinc in the form of zinc blende and related materials.
The method is applicable to gold contents from 0,5 g/t to 12 g/t.
