DESCRIPTION

BS 7020-5.2:1993


This standard BS 7020-5.2:1993 Analysis of iron ores. Methods for the determination of silicon content is classified in these ICS categories:
  • 73.060.10 Iron ores

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.


Describes a method for the determination of silicon contents between 0.1% (m/m) and 5.0% (m/m) in iron ores.
