Gives a method, free from mercury pollution, for determining total iron content in iron ores by silver reduction and potassium dichromate titration. Applicable to a concentration range of 30% to 72% of iron in natural iron ores, iron ore concentrates and agglomerates, including sinter products, containing not more than 0.1% Cu. Contents of vanadium normally present in iron ores are without effect. Covers normative references, principle, reagents, apparatus, sampling and samples, procedure, expression of results and test report.
