This International Standard specifies a fire assay gravimetric and flame atomic absorption spectrometricmethod for the determination of the mass fraction of gold and silver in copper, lead and zinc sulfideconcentrates as follows:? Copper concentrates:The method is applicable to the determination of mass fractions of gold from 0,5 g/t to 300 g/t and ofmass fractions of silver from 25 g/t to 1 500 g/t in copper sulfide concentrates containing mass fractions ofcopper from 15 % to 60 %.? Lead concentratesThe method is applicable to the determination of mass fractions of gold from 0,1 g/t to 25 g/t and of massfractions of silver from 200 g/t to 3 500 g/t in lead sulfide concentrates containing mass fractions of leadfrom 10 % to 80 %.? Zinc concentratesThe method is applicable to the determination of mass fractions of gold from 0,1 g/t to 12 g/t and of massfractions of silver from 10 g/t to 800 g/t in zinc sulfide concentrates containing mass fractions of zinc up to60 %.
