Evolution of binders for iron ore pelletizing Induration technologies Challenges and innovations in iron ore pelletizing 2. 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.
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.
20 Mt/a iron ore fines. The fast depletion of high-grade iron ore fines, increased industrial demand and an increase in iron ore prices have necessitated the exploitation and use of low-grade iron ore fines in the steel-making process after beneficiation. Thus, the beneficiation of low-grade iron ores by removing the
