Iron ore fluxed pellets and their physical properties ...

1985-6-1  The moisture content of iron ore fluxed pellets was calculated proportionally according to the amount of water required by pure iron ore and pure limestone pellets (13.5% and 16.5% respectively). Therefore, a fluxed charge containing 10% limestone needs 13.8% water and a charge containing 20% limestone needs 14.1% water content.
