Describes 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 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 Table1, in natural iron ores, iron ore concentrates and agglomerates, including sinter products. Table1 Mass-fraction ranges Element Range of mass fractions % Al 0,07 to 3,30 Ca 0,012 to 6,80 Mg 0,008 to 1,90 Mn 0,012 to 1,70 P 0,011 to 1,60 Si 0,44 to 9,40 Ti 0,018 to 0,17
