标准摘要
[中文适用范围]： 本标准规定了测定硫化锌精矿中银含量的酸溶解火焰原子吸收光谱法。 该方法适用于闪锌矿形式锌含量高达 60% (m/m) 的硫化锌精矿及相关材料中银的测定。 本方法适用于银含量10g/t～500g/t。 [外文原描述]： ISO 15247:2015 specifies an acid dissolution and flame atomic absorption spectrometric method for the determination of silver content of zinc sulfide concentrates. The method is applicable to the determination of silver 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.
