A model of ore sintering reactivity can be built with the aid of sinter pot tests appropriately designed to simulate ores, mixtures and process conditions inherent to each industrial plant. The model can be used to guide changes in ore mixture for a given need of process and/or sinter performance. The model built with the series of experiments used in this work indicated: Porous ores were appropriate for accelerating the process, while compact ores control sinter mechanical strength. Hematite ores showed superior performance than predominantly goethite ores. Hematite-middling crystallized-porous ores were the most reactive ores according to the combined concept of higher productivity and sinter mechanical strength.
