Improved dewatering of iron ore fines by the use of

The washing of the iron ore fines results in a moisture of about 11–14% in the fines and about 4% in the sized ore. The moisture content goes up to 16–18% in the fines during the monsoon season. Indian iron ore contains hematite and goethite as the major iron bearing minerals.
