    Abstract - (Show below) - (Hide below)

    Applicable to lead or zinc contents in the range 0.001 to 0.5% (m/m) in natural iron ores, and iron ore concentrates and agglomerates including sinter products.

    Scope - (Show below) - (Hide below)

    This International Standard specifies a flame atomic absorption spectrometric method for the determination of the lead and/or zinc content of iron ores.

    This method is applicable to a concentration range of 0,001 to 0,5 % (m/m) of lead and 0,001 to 0,5 % (m/m) of zinc in natural iron ores, and iron ore concentrates and agglomerates including sinter products.
