First, the sintering bed was assumed as a particle packed bed and was treated by means of the porous medium hypothesis;
Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The ‘recipe’ for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests
Mar 19, 2008· Iron ore, its beneficiation and agglomeration - as required for iron and steel industry: A. Iron Ore: A naturally occurring mineral from which iron (Fe) metal is extracted in various forms viz Hot metal/ DRI etc.. B. Types of Ore: Two major varieties used for iron making are Haematite Ore ( containing Ferric Oxide - Fe2O3) and Magnetite Ore (containing Ferro-Ferric Oxide – Fe3O4).
Iron ore can also be pre-treated before traded. For instance, sinter feed is made from DSO and pellets are made by taking very fine iron ore and agglomerating them with moisture and a binder to form balls. Pellets are essentially artificial lump.
The process of mining low-grade iron ore, or taconite, requires massive resources.Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required. Some of the equipment includes diamond-bit rotary drills, hydraulic shovels and loaders, water-wagons, production trucks and heavy duty conveyors.

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 fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...
A binder for use in agglomerating finely divided iron ore materials, e.g., concentrates, is prepared from an iron-bearing material known on the Mesabi Range of Minnesota as ''''paint rock.''''
