Iron ores. Determination of various elements. Inductively coupled plasma atomic emission spectrometric method Ingestion-build-183098 Who is ISO/TS 21139‑21 for1 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. Table 1 Mass fraction ranges Element Range of mass
