Pelletization
1.2.2.2.1 Pelletization. Pelletization is the most popular method of converting iron ore fines into agglomerates. Early work on pelletization took place in Sweden, but commercialization at large scale first occurred in the United States [13]. In this case, processing technologies for low-grade taconite ores were needed due to exhaustion of …
11.23 Taconite Ore Processing
Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.

Iron Ore Pelletizing Process: An Overview
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
Applications of Iron Ore Pellets
What Is Iron Ore Pelletization Process. The process of pelletization begins with the use of finely powdered grains of iron ore. These grains are then converted into balls. This iron ore concentrate is next heated and dried over high temperatures. The next step involves grinding this dried residue, with the addition of Bentonite which is a ...
pelletization process by Kshirod | PPT
Pelletization is the process of making spheres of uniform quality iron ore with high carbon content. Iron ore is pelletized so that it can efficiently flow through a blast furnace for smelting. The process involves mixing iron ore fines with additives like limestone, dolomite, and bentonite.

Iron Ore Pelletization: Part I. Fundamentals
ABSTRACT The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet. Meeting these requirements …
