Iron ores -- Determination of sodium content -- Flame atomic absorption spectrometric method

This International Standard specifies a flame atomic absorption spectrometric method for the determination of the sodium content of iron ores.

This method is applicable to sodium contents between 0,002 % (m/m) and 1,0 % (m/m)1) in natural iron ores, iron ore concentrates and agglomerates, including sinter products.

1) The method has not been tested on ores containing more than 0,50 % (m/m) of sodium (see annex B). However, it is possible to extend its application to 1,0 % (m/m) using the calibration Standards prepared.
