Abstract


The fitness for granulation of an ore mixture used to make a series of sintering in a pilot plant is studied. The quality indexes and the phases composition of sinterings is determined. The best sintering structure is checked. A serie of iron ores is classified as the granulation index (G index). The G index evolution of the ore mixtures used by ACERALIA for the last years is shown. An increase in productivity and a decrease in coke consumption in the sinter strand is observed as the G index improves.
