Copper and nickel sulfide ores and concentrates — Determination of total chlorine content — Alkaline fusion and potentiometric titration method

Minerais et concentrés de sulfure de cuivre et de sulfure de nickel — Détermination de la teneur totale en chlore — Méthode par fusion alcaline et par titrage potentiométrique

Abstract / scope

This document specifies an analytical method for the determination of total chlorine content using alkaline fusion and potentiometric titration.

This method is applicable to copper and nickel sulfide ores and concentrates having chlorine content in the following ranges:

a) Method 1: 80 µg/g to 4 300 µg/g

b) Method 2: 70 µg/g to 4 300 µg/g
