This document specifies a potentiometric titration method for the determination of total iron content
of iron ores, using potassium dichromate as titrant after reduction of the iron(III) by tin(II) chloride
and 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 fraction
of 72,02 % in natural iron ores and iron ore concentrates and agglomerates including sinter products.
