Quantification of Moisture Contents in Iron and

The standard method to determine the total iron content in ores is the ISO 2597-2:2008, which makes use of a titrimetic method with potassium dichromate as the titrant. Prior the analysis, the material should be dried in order to remove the moisture and hence the results can be given on a dry sample basis.
