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 ...

1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
