This International Standard specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of cobalt in iron ores.<\/p>\n
This method is applicable to a mass-fraction range of 0,000 7 % to 0,06 % of cobalt in natural iron ores, iron ore concentrates and agglomerates, including sinter products.<\/p>\n
