1 Scope
This International Standard specifies a method for the determination of aluminium,
calcium, phosphorus, magnesium, manganese, silicon and titanium in iron ores by inductively
coupled plasma atomic emission spectrometry (ICP-AES).
This method is applicable to the mass-fraction ranges given in Table 1, in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
