| Resumen: | This part of ISO 2598 specifies two gravimetric methods for the determination of the silicon content of iron ores. These methods are applicable, with certain limitations, to silicon contents between 1 % (m/m) and 15 % (m/m) in natural 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 0,1 % (m/m). It is recommended for lower grade ores having a high content of amphoteric elements. Method 2 can be used for ores having a fluorine content greater than 0,1 % (m/m). It is recommended for high grade ores having a low content of gangue.
