Iron Ore Pellets - Iron Ore

These reactions can include the dehydration of hematite or the oxidation of magnetite; in many cases "fluxed pellets" are produced by the addition of limestone or dolomite to the balling feed. These additions react with the gangue in the iron ore to enhance the performance of the pellets in certain downstream processing steps. Iron ore ...
