Iron ores. Determination of cobalt. Flame atomic absorption spectrometric method has-hardcopy BS EN 3707 is a1 Scope This International Standard specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of cobalt in iron ores. 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.
