    Abstract - (Show below) - (Hide below)

    ISO 4689-2:2017 specifies a combustion/titration method for the determination of the sulfur content of iron ores.

    This method is applicable to sulfur contents between 0,002 % (mass fraction) and 0,25 % (mass fraction) in natural iron ores, iron ore concentrates, and agglomerates, including sinter products. The results are not affected by the presence of fluoride.
