Copper, lead, zinc and nickel sulfide concentrates. Determination of arsenic - Acid digestion and inductively coupled plasma atomic emission spectrometric method LONG_TITLE ISO 15686-51 Scope This International Standard specifies an acid digestion and inductively coupled plasma atomic emission spectrometric (ICP AES) method for the determination of the mass fraction of arsenic in copper, lead, zinc, and nickel sulfide concentrates as follows: a) for copper sulfide concentrates, the method is applicable to the determination of mass fractions of arsenic from 0,05 % to 2,0 %; b) for lead sulfide concentrates, the method is applicable
