GB/T 3884.2-2012 《Methods for chemical analysis of copper concentrates - Part 2: Determination of gold and silver contents - Flame atomic absorption spectrmetric method and fire assay method》 Related products

This standard specifies methods for the determination of gold and silver content in copper concentrates, which are applicable to the determination range of silver 10.0 g/t300.0 g/t, gold 0.50 g/t40.00 g/t and silver 50.0 g/t~ 2500.0 g/t, respectively. The gold and silver content can be accurately detected by flame atomic absorption spectroscopy (AAS) and fire assay. This standard provides reliable methodological support for the analysis of precious metal content in copper concentrates and is suitable for mineral resource assessment and quality control.
