Influence of particle size distribution of iron ore fines ...
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 ...

Iron Ore Tailings: Characterization and Applications
In general, the processing of iron ore involves operations to modify the particle size distribution and to increase the iron content, without changing the chemical or physical identity of the minerals.13 In ores where the iron content is already high (e.g., Carajás-Brazil), the processing, normally, is a simple grinding and separating

Numerical study of the dynamic behaviour of iron ore ...
Iron ore granulation process is simulated by the discrete element method to understand the dynamic behaviour of iron ore particles. The results show that the macroscopic particle flow transits from rolling regime to cascading regime after water addition, with the angle of repose of particles increasing and the level of particle size segregation decreasing.
