Omfattning
This patt of ISO 2598 specifies two gravimetric methods for the determination of the Silicon content of iron ores. These methods are applicable, with certain Iimitations,
to Silicon contents between 1 % (m/m) and 15 % (m/m) in natura1 iron ores, iron ore concentrates and agglomerates, including Sinter products. Method 1 is not applicable to iron ores having a content of reducing agents greater than 2 % (m/m),
for instance Pyrite, or to ores having a fluorine content greater than 0,l % (m/m). lt is recommended for lower grade ores having a high content of amphoteric elements.
Method 2 tan be used for ores having a fluorine content greater than 0,l % (m/m). lt is recommended for high grade ores having a low content of gangue.
NOTE 1 For ores having a silicon content less than 5 % @/WZ), the method specified in ISO 2598-2: -11, Iran ores - Determination of Silicon content - Part 2: Reduced
moiybdosilicate spectrophotometric method, is preferable.
