Effect of Iron Ore Pellet Size on Metallurgical Properties MDPI

Iron ore pellets are small and hard spherical particles agglomerated from a fine iron ore concentrate. They are used in the blast furnace process to produce hot metal. The diameter of blast furnace pellets is usually between 8 and 16 mm. In this study, a batch of magnesia iron ore pellets was first sieved into particle sizes of 810 mm, mm, mm and 1620 mm, and the four ...

Study of Temperature Profile in the Induration of Magnetite Iron Ore ...

The pelletisation study of magnetite iron ore fines starts with green balling using limestone and bentonite as additives. Heating cycle of iron ore pellets is one of the prime segments of the whole pelletisation process. Drying, preheating, firing and cooling processes are collectively named as heating cycle of the process. A temperature profile is maintained throughout the induration process ...

Iron ore filtration process improvement through pH modification

The present study presents the effect of pH reduction in iron ore slurry for an iron ore filtration process. A reduction on moisture content and increase on filters throughput was proposed by the pH modification. The experimental procedure included bench scale tests and industrial scale up of the observed results. Additionally, Langelier's saturation index was applied to determine the ...
