GB/T 8151.19-2012 Methods for chemical analysis of zinc sulfide concentrates—Part 19:Determination of silver and gold contents—Fire assay and flame atomic absorption spectrometric method using scorification or cupellation
Abstract
This part of GB/T 8151 specifies the methods for determining the gold and silver content in zinc sulfide concentrates by fire assay and flame atomic absorption spectrometry.
This part is applicable to the determination of gold and silver content in zinc sulfide concentrates with a zinc content not exceeding 60% (by mass). The determination range is: silver 10 g/t to 500 g/t, gold 0.1 g/t to 12.0 g/t.
