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 lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

In general, pelletization of iron ore is a process where the feed is a mixture of highgrade hematite/magnetite ore mixed with binder and coke breeze as additives to form pellets for the production of iron and steel [5]. Such types of initiatives can eradicate the crises of highgrade iron ore demand as pellet feed material as well as support ...

The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted ...
