Fundamental pore formation mechanisms in iron ore sinter and pellets were investigated. The study was first conducted with tablets made from iron ore and limestone particles, with and without addition of coke, and the results were then tested and proved in real pellets made with a laboratory ball mill and in real sinter made with a sintering pot.

Iron Ore Smelting Process Brighthub Engineering. Large scale iron ore smelting has been carried out in numerous types of blast furnaces since the industrial revolution, with the basic ingredients of coke, iron ore and limestone remaining unchanged, being loaded into the blast furnace from where the molten iron is tapped into molds.
"Ironore is also exported in a valueadded, pelletized form. Full exemption from export duty is being provided to iron ore pellets to encourage the value addition process for fines" Further, Budget speech of 201213 : "Toencourage enrichment of lowgrade iron ore, of which we have huge
addition of 20% of LKAB iron ore concentrate to the sinter blend, has no significant impact on productivity. On the other hand, addition of 20% pellet screenings prove to have a positive effect compared to the reference case. From the results, the addition of 20% pellet screenings increase the productivity by slightly more than 7%.

Conclusions Following conclusions were drawn from the present study: 1. It has been possible to use fluxed iron ore pellets using iron ore and lime fines as a raw material to minimize flux input in Blast Furnace as a limestone and avoid bentonite addition as binder in conventionally prepared pellets. 2.
The rapid growth in production by the iron ore producers has resulted in a shift in the nature of iron ores that are being mined and sold. For Australia this means a change from the traditional Brockman hematite ores to goethitic Marra Mamba ores, products blended from multiple separate mines, and channel iron .

The term iron ore pellets refers to the thermally agglomerated substance formed by heating a variable mixture of iron ores, limestone, olivine, bentonite, dolomite and miscellaneous iron‐bearing materials in the temperature range 1250 to 1350°C. The iron ore pellets are used principally as a
The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets.
