DESCRIPTION

PD ISO/TS 2597-4:2019


This standard PD ISO/TS 2597-4:2019 Iron ores. Determination of total iron content is classified in these ICS categories:
  • 73.060.10 Iron ores

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.
