This document specifies the method for the determination of water soluble chloride content in iron ores using ion-selective electrodes. This document is applicable to the determination of water soluble chloride content in natural iron ores, iron ore concentrates, sinters and pellets. The determination range (mass fraction) is: 0.007% ~ 0.1%. NOTE: the water soluble chloride content in iron ores refers to the chlorine obtained by leaching iron ores with aqueous solution under near-neutral conditions.
