This document specifies an analytical method for the determination of total chlorine content using alkaline fusion and potentiometric titration.<\/p>\n
This method is applicable to copper and nickel sulfide ores and concentrates having chlorine content in the following ranges:<\/p>\n
Method 1: 80 \u00b5g\/g to 4 300 \u00b5g\/g<\/p>\n<\/li>\n
Method 2: 70 \u00b5g\/g to 4 300 \u00b5g\/g<\/p>\n<\/li>\n<\/ol>\n
