When the iron ore particle size decreased to 38 m, almost the whole reduction of the iron ore achieved at 1200 C. The X ray diffraction analysis of this mixture showed that metallic iron phase occupied an important position in the residue. This indicated that the iron ore particle size of 38 m was sufficient to complete the reduction. 3.2.
Jun 01, 1988 The effects of feed properties on the granulation of iron ore sinter feed have been studied using simplified sinter mixes. A measure of granulation effectiveness, x 0.5, has been defined as the particle size at which half the particles act as adhering particles and half as nuclei particles.High values of x 0.5 correspond to large mean granule sizes. . The granulation effectiveness is a strong.
Abstract. Fundamental pore formation mechanisms in iron ore sinter and pellets were investigated. The study was first conducted with tablets made from iron ore and limestone particles, with and without addition of coke, and the results were then tested and proved in real pellets made with a laboratory ball mill and in real sinter made with a sintering pot.

Study of iron ore sintering Influence in the reduction by hydrogen. By Victor Bridi Telles. Abstract. The materials were characterized by particle size analysis, chemical analysis, X ray diffraction optical and scanning electron microscopy. The inicial sintering tests aimed to produce return fines for subsequent sintering.
Aug 01, 2020 This study aimed to investigate the influence of the particle size distribution of iron ore fines (IOF) on the liquefaction potential of bulk cargoes for maritime transport. The correlation of liquefaction potential with IOF particle size distribution is of great interest to ore transport companies, as they have a variety of IOF sizes that can be mixed to improve liquefaction potential.
2) Ores with a particle size of 3–5 mm and limestone with a particle size smaller than 0.125 mm were mixed to achieve a CaO Ore ratio of 0.1 and subsequently granulated by hand by adding water in a small petri dish. The granulated particles were charged in a Ni crucible and heated in a vertical electric furnace. The samples were.
