Scope
This part of GB/T 3884 specifies the determination methods for the gold and silver content in copper sulfide concentrates—the fire assay gravimetric method and the flame atomic absorption spectrometry method.
This part is applicable to the determination of the gold and silver content in copper sulfide concentrates with a copper content of 15% to 60%. The determination range is Au 0.5 g/t to 300.0 g/t, and Ag 25 g/t to 1,500 g/t.
