Present pelletization practices are facing problems to handle high loss on ignition (LOI) concentrate generated from goethitic-hematite iron ore containing higher goethite, gibbsite, and kaolinite.These minerals need to completely release their LOI in the preheating zone of pellet induration process. If it is not, crack develops in the pellet, …

In the production of iron ore concentrate pellets, binders are required to improve pellet green strength.The most popular binder for this purpose is bentonite clay, which is added at a rate of approximately 0.5–1.0% by weight of moist concentrate. Bentonite is a significant cost item in iron ore pelletization, and also contributes …

In 2011, over 2.8 billion metric tons of iron ore was produced worldwide [3].After its extraction, the iron ore is mechanically divided to produce three different qualities; fines (<6.3 mm), lump (6.3–30 mm) and pellets (9.5–16 mm) [4].Since 98% of the iron ore produced is used to make steel, it is said to be "more integral to the global …

Image analysis of SEM micrographs may be used for quantitative determination of morphological features in iron ore pellets. However, the porosity of iron ore green pellets after drying is complex and has two different origins: the continuous porosity between the grains packed during balling and large cavities caused by bubble …

This study corroborates that the iron ore mineralogy has significant effects on green pellet growth and its properties by both experimental and mathematical arguments. In this context, three iron ore samples with different loss on ignition (LOI): 2.64, 4.85 and 9.19 wt.% were taken. The mineralogical differences were investigated through …

Abstract Metallurgical properties are determined by the structure of pellets at the macrolevel as well as at the level of minerals and elements. The goal of this work is to analyze changes in the porosity of iron-ore pellets during their lifecycle, from pelletizer to full reduced state. The model used in this work relies on several assumptions: (1) the …
