Recrystallization of Fe 2 O 3 During the Induration of Iron Ore Oxidation Pellets 331 the dry balls were put into a corundum crucible and pushed into the preheating zone of the furnace step by step, preheated at the given temperature for a given period.
Iron ore pelletizing systems - liming
Iron ore can be upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don’t need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.

Modeling and simulation of iron ore pellet drying and . We present a mathematical model of iron ore pellet drying and induration in an industrial scale application and validate it against measured data The model is based on the laws of mass and heat transfer and incorporates both physical and stone processes The partial differential equations of the process kinetic model involve derivatives ...
Interaction between iron ore and magnesium …
To eliminate the adverse effect of incompletely mineralized magnesium additive on pellets strength, clarify the interaction between additives and iron ore during the induration process, two types of interaction couples were prepared and scanning electron microscopy-Energy dispersive spectrometer was used to study the diffusion of elements and phase transformation during the induration.
Understanding reactions in iron ore pellets
The induration furnace for iron ore pellets was originally designed to process concentrates with high contents of magnetite. To support the use of haematite concentrates, internal fuel was added ...
Introduction to Iron ore Pellets and Pelletizing …
Process technology. There are four stages involved in the production of iron ore pellets. These stages consist of (i) raw material preparation, (ii) formation of green balls or pellets, (iii) induration of the pellets, and (iv) cooling, storage and transport of pellets.
Study on the Induration Cycle During Pelletization of ...
Several investigations1-7 were carried out to study the induration of iron ore green pellets. However, most of such studies have been based on either with total induration process or modelling on the induration process. Relatively few studies6 have been reported on the drying stage of the induration process.

Pelletizing process and raw materials The iron ore is mined mostly from open pit deposits through mining operations and the raw product, run of mine, is subjected to mineral processing.
PLASMA HEATED FURNACE FOR IRON ORE PELLET …
In the present pelletizing apparatus, the induration of iron ore concentrate pellets is achieved in a tunnel furnace heated by plasma torches, wherein the generation of by the conventional iron ore pelletizing processes is reduced by using electricity powered plasma torches instead of burning natural gas, heavy oil or pulverized coal in burners, thereby reducing considerably industrial ...
Multi-objective optimization of iron ore induration ...
Induration in steel industries is the process of pelletizing iron ore particles. It is an important unit operation which produces raw materials for a subsequent stone reduction in Blast Furnace. Of the enormous amount of energy consumed by Blast Furnace, a …

The induration process of oxidized pellet, containing the oxidation of magnetite phase (Fe3O4) and the sintering of oxidized magnetite phase (hematite–Fe2O3), is significant to obtain sufficient pellet strength. The current study focuses on the induration mechanisms of MgO flux pellet in terms of the oxidation process of Fe3O4 and densification process of the pellet.
