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 fine ores resulting from the concentration process must be agglomerated for use in iron and steelmaking.

The earliest attempts to float iron oxide minerals involved the use of anionic collectors such as oleic acid or sodium oleate. Such a process was used at the Cuyuna Range plant which processed manganiferous iron ore in 1931. One of the successful applications of anionic flotation process was the iron ore flotation plant at Marquette county ...

The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
