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 0,0002 to 0,1500,0002 to 0,150 V 0,0030 to 0,0240,0030 to 0,024 Ti 0,0150 to 0,1200,0150 to 0,120 Cu 0,0014 to 0,2500,0014 to 0,250 Ni 0,0050 to 0,0900,0050 to 0,090 Cr 0,0040 to 0,015 Ba 0,0028 to 0,035 Co 0,0020 to 0,100
