SUMMARY:

The iron ore is constituted in larger occurrence of hematite (Fe2O3), being able to be found in other types of rocks as the magnetite (Fe3O4) and goethite FeO(OH), being these the main mineral-ore of the Brazilian iron deposits. In order to better understand the origin of pellet feed, which is a concentrate with high iron content, this work aimed to: raise a theoretical reference about iron ore, as well as its deposits, genesis, main minerals found in iron deposits, considerations and production process. In addition, to report on the use of iron ore concentrate in the pelletizing process. In the pelletizing process, the objective is to aggregate the ore fines (size <0.15 mm) into pellets with granulometry and quality for their direct use in the steelmaking process. In view of this, the general objective of this study is to briefly review the function of pellet feed as the main raw material in the iron ore pelletizing process. The adopted methodology was the bibliographical research that has as characteristic the reading, analysis and interpretation of books, periodicals, legal texts and other documents that can serve of literary source for the proposed theme, besides applying an experimental methodology with the objective of being a important instrument of knowledge and information for professionals in the field, and more specifically in mineral processing area. In general, it is concluded that to produce uniform and good quality pellets, it is necessary to take into account the wide variety of properties of the ores, such as their mineralogy, particle size and shape, crystalline habit and chemical composition. Furthermore, it is important to mention that the project aims to contribute to the analysis, improvement and expansion of studies, aiming to improve the mechanical properties of the pellets through the addition of binding agents.
