This part of ISO9682 specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of manganese in iron ores.
This method is applicable to a mass-fraction range of 0,01%to 2,5%of manganese in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
