Zinc sulfide concentrates — Determination of silver and gold contents — Fire assay and flame atomic absorption spectrometric method using scorification or cupellation
This International Standard specifies a fire assay and flame atomic absorption spectrometric procedure for the determination of silver and gold contents of zinc sulfide concentrates.
The method is applicable to the determination of silver and gold in zinc sulfide concentrates containing up to 60 % (m/m) zinc in the form of zinc blende and related materials.
The method is applicable to silver contents from 10 g/t to 500 g/t and gold contents from 0,1 g/t to 12 g/t.
