Iron ores. Determination of phosphorus content. Titrimetric method
This International Standard specifies a titrimetric method for the determination of the phosphorus content of iron ores, using hexaammonium heptamolybdate (ammonium molybdate).
This method is applicable to a concentration range of 0,10 % (m/m) to 5,0 % (m/m)1) of phosphorus in natural iron ores, and iron ore concentrates and agglomerates including sinter products.
This International Standard provides a quality control method for the determination of phosphorus by titration; however, the method cannot be used for referee purposes.
