This document specifies a photometric titration method using EDTA for the determination of the total iron content of iron ores.<\/p>\n
This method is applicable to a concentration range of a mass fraction of 37,00 % to 72,00 % of total iron in natural iron ores, iron ore concentrates and agglomerates, including sinter products.<\/p>\n
