Iron ores. Determination of trace elements. Plasma spectrometric method. | Status: Confirmed, Current

1 Scope This document specifies a method for the determination of phosphorus, vanadium, titanium, copper, nickel, chromium, barium and cobalt in iron ores, by inductively coupled plasma atomic emission spectrometry (ICP-AES). This method is applicable to the concentration ranges (mass fraction) given in Table 1, in natural iron ores, iron ore concentrates and agglomerates, including sinter products. Table 1 — Concentration ranges Element Concentration range for referee purpose % (mass fraction) Concentration range for non-referee purpose % (mass fraction) P 0,000 2 to 0,150 0,000 2 to 0,150 V 0,003 0 to 0,024 0,003 0 to 0,024 Ti 0,015 0 to 0,120 0,015 0 to 0,120 Cu 0,0014 to 0,250 0,001 4 to 0,250 Ni 0,005 0 to 0,090 0,005 0 to 0,090 Cr 0,004 0 to 0,015 Ba 0,002 8 to 0,035 Co 0,002 0 to 0,100
