This part of ISO5418 specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of copper in iron ores.
This method is applicable to a mass-fraction range of 0,004%to 0,8%of copper in natural iron ores, and iron ore concentrates and agglomerates, including sinter products.
