This part of ISO 2598 specifies a reduced molybdosilicate spectrophotometric method for the determination of the silicon content of iron ores.
This method is applicable to silicon contents be­tween 0,1 % (m/m) and 5,0 % {m/m) in natural iron ores, iron ore concentrates and agglomerates, in­cluding sinter products, especially for ores contain­ing fluorine.
The fluorine content of the sample does not affect the determination.
