This International Standard specifies a fire assay gravimetric and flame atomic absorptionspectrometric method for the determination of the mass fraction of gold and silver in copper, lead, andzinc sulfide concentrates as follows.— Copper concentratesThe method is applicable to the determination of mass fractions of gold from 0,5 g/t to 300 g/t andof mass fractions of silver from 25 g/t to 1 500 g/t in copper sulfide concentrates containing massfractions of copper 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 andof mass fractions of silver from 200 g/t to 3 500 g/t in lead sulfide concentrates containing massfractions of lead from 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 andof mass fractions of silver from 10 g/t to 800 g/t in zinc sulfide concentrates containing massfractions of zinc up to 60 %.
