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.
