Resumo
The present study demonstrates the effect of the different morphological types on the cold crushing
strength (CCS) of heat-treated iron ore pellets. Blends with different iron ore oxides morphologies were
subjected to grinding, filtering and pot grate tests on industrial scale trials. Results of grinding tests
showed the hematite-goethite aggregates the most influent one on energy consumption. The martitichematite
content was straightly related to the final moisture and filtration productivity. The hematitegoethite
aggregates, therefore the goethite content, influences CCS, being the lower the goethite
content, the higher the values of CCS.
