This document specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of potassium in iron ores.<\/p>\n

This method is applicable to mass fractions of potassium between 0,002 5 % and 0,52 % in natural iron ores, iron ore concentrates and agglomerates, including sinter products.<\/p>\n
