This document specifies a flame atomic absorption spectrometric method for the determination of the nickel mass fraction of iron ores.
This method is applicable to mass fractions of nickel between 0,001 % and 0,10 % in natural iron ores, iron ore concentrates and agglomerates including sinter products.
This method is not appropriate for referee purposes.
