Lead sulfide concentrates — Determination of silver and gold contents — Fire assay and flame atomic absorption spectrometric method using scorification or cupellation
硫化铅精矿——银和金含量的测定——燃烧分析和火焰原子吸收光谱测定法(使用焦化或铜化)
This International Standard specifies a fire assay and flame atomic absorption spectrometric procedure for the determination of silver and gold contents of lead sulfide concentrates.
The method is applicable to the determination of silver and gold in lead sulfide concentrates containing 10 % (m/m) to 80 % (m/m) lead.
The method is applicable to silver contents from 200 g/t to 2 000 g/t and gold contents from 0,1 g/t to 25 g/t.
