This International Standard specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of magnesium in iron ores.
This method is applicable to mass fractions of magnesium between 0,010 % and 2,00 % in natural iron ores, iron ore concentrates, and agglomerates, including sinter products.
