depend on each ironmaking furnace and thoserequirements influence the operation ofthe iron ore pelletizing plant. The idea of rolling moist fine ore in a drum to form balls and then drying and firing it was first patented by A. G. Andersson in Sweden in 1912. Further development was performed to bring the idea to reality. In 1943, E. W. Davies and co-workers demonstrated the process using an

The iron pelletizing process is often associated with low grade iron ore following a range of liberation techniques to prepare and make suitable for the blast furnace. In summary, pelletizing is achieved by combining the iron ore with water and a specific binder which is then rolled up in drum to produce relatively uniform pellets which can then be easily handled in downstream processes.
