DESCRIPTION

BS ISO 2597-2:2019 - TC


This standard BS ISO 2597-2:2019 - TC Tracked Changes. Iron ores. Determination of total iron content is classified in these ICS categories:
  • 73.060.10 Iron ores

This document specifies two titrimetric methods, free from mercury pollution, for the determination of total iron content in 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 either dilute potassium dichromate (Method 1) or perchloric acid (Method 2).

Both methods are applicable to a concentration range of 30 % mass fraction to 72 % mass fraction of iron in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
