This document specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of calcium in iron ores.<\/p>\n
This method is applicable to mass fractions of calcium between 0,010 % and 8,00 % in natural iron ores, iron ore concentrates, and agglomerates, including sinter products.<\/p>\n
