High melting point slag would produce sufficient bonding strength to limit swelling and low melting point slag enhances swelling. In acid pellets, reduction is accompanied by the reaction between Fe 2+ and SiO 2 to form low melting point phase, fayalite (Fe 2 SiO 4 ) that melts at 1175°C [6, 7].
Iron ore and iron ore pellets are important sources of iron for manufacturing steel. The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries, such as China and India. However, the content of iron ore in deposits has deteriorated and lowgrade iron ore has been processed.

At Rio Tintos giant private iron ore railway in the Pilbara, a relatively lowcost project to overhaul 180 locomotives to run without drivers looks like being up to three years late, costing the miner up to 30 million tonnes a year of iron ore export capacity.
But, the hematite pellet does not contain lower iron oxides due to which it requires higher induration temperature (1300ºC) and consumes higher energy than magnetite pellet. The required induration temperature can be lowered if the diffusion bond formation is enhanced or some low melting compound is added in pellet for slag bond formation.
