This document specifies a potentiometric titration method for the determination of total iron contentof iron ores, using potassium dichromate as titrant after reduction of the iron(III) by tin(II) chlorideand titanium(III) chloride. The excess reductant is then oxidized by potassium dichromate solution.This method is applicable to total iron contents between a mass fraction of 29,04 % and a mass fractionof 72,02 % in natural iron ores and iron ore concentrates and agglomerates including sinter products.Cross References:ISO 3082ISO 1042ISO 7764ISO 648ISO 2596ISO Guide 35ISO 5725-2
