Scope

This Part of GB/T 6730 specifies the determination of total iron content by
titration of potassium dichromate after reduction of iron with titanium (III)
chloride.
This Part applies to the determination of total iron content in natural iron ores,
iron concentrates, and agglomerations, including sintered products. The
determination range (mass fraction): 30.0%~72.0%.
