Copper, lead, zinc and nickel sulfide concentrates - Determination of arsenic - Part 1: Iron hydroxide concentration and inductively coupled plasma atomic emission spectrometric method - First Edition
 N 13547-1

Annotation

This International Standard specifies an iron hydroxide concentration and inductively coupled plasma atomic emission spectrometric (IPC-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 fraction of arsenic from 0,05% to 2,0%;

b) for lead sulfide concentrates, the method is applicable to the determination of mass fractions of arsenic from 0,05% to 1,0%;

c) for zinc sulfide concentrates, the method is applicable to the determination of mass fractions of arsenic from 0,05% to 0,6%;

d) for nickel sulfide concentrates, the method is applicable to the determination of mass fraction of arsenic from 0,05% to 1,0%.
