agglomerating iron ore in general use for blast furnaces. Pelletizing is commonly used when the ore needs to be shipped great distances to the blast furnace due to the better durability of pellets [5, 6]. The pelletization procedure consists of agglomerating the ore powder into "green" balls or
Abstract. Systematic measurements of shrinkage kinetics of a pure hematite reagent powder and of a commercial magnetite concentrate are presented, and rate constants and activation energies evaluated. The discussion links the results of pellet induration research with sintering theory, developed in support of powder metallurgy and ceramics.
