This International Standard specifies a fire assay gravimetric and flame atomic absorption spectrometric method for the determination of the mass fraction of gold and silver in copper, lead, and zinc sulfide concentrates as follows.
-
Copper concentrates
The method is applicable to the determination of mass fractions of gold from 0,5g/t to 300g/t and of mass fractions of silver from 25g/t to 1500g/t in copper sulfide concentrates containing mass fractions of copper from 15%to 60%.
-
Lead concentrates
The method is applicable to the determination of mass fractions of gold from 0,1g/t to 25g/t and of mass fractions of silver from 200g/t to 3500g/t in lead sulfide concentrates containing mass fractions of lead from 10%to 80%.
-
Zinc concentrates
The method is applicable to the determination of mass fractions of gold from 0,1g/t to 12g/t and of mass fractions of silver from 10g/t to 800g/t in zinc sulfide concentrates containing mass fractions of zinc up to 60%.
