    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.
