标准范围
This document specifies two titrimetric methods, free from mercury pollution, for the determination
of total iron content in iron ores, using potassium dichromate as titrant after reduction of the iron(III)
by tin(II) chloride and titanium(III) chloride. The excess reductant is then oxidized by either dilute
potassium dichromate (Method 1) or perchloric acid (Method 2).
Both methods are applicable to a concentration range of 30 % mass fraction to 72 % mass fraction of
iron in natural iron ores, iron ore concentrates and agglomerates, including sinter products.
