Effects of alumina in iron ore - ResearchGate

Effect of Alumina in Iron ore Sintering . The most harmful effect of alumina is to worsen the sinter RDI, which increases as the alumina content rises. Industrial experience with the blast furnace shows that. within a 10-10.5% CaO content range an increase of 0.1% in the alumina content raises the RDI by 2 …

Effects of Alumina on Sintering Performance of Hematite ...

However, due to the limited reserves and increasing depletion of high-grade iron ore resources, the alumina content of iron ores is expected to increase gradually. While the increase in such constituents is relatively slow over a long period, it has still caused problems for blast furnace operators.


Major problem faced with the Indian iron ore is that though they are very rich in iron content they also have a high content of gangue material like silica and aluminium which obstruct the iron and steel production as the performance of the blast furnace lowers. Iron ore sample found is a part of banded iron ore formation.

Influence of Alumina on Iron Ore Sinter Properties and ...

Apr 23, 2010 · Due to depletion of high grade iron ore resources, alumina content in the iron ore fines is expected to increase gradually. Ore with higher alumina content is usually expected to be detrimental in forming the sinter matrix, if sintered alone, due to the low reactivity of alumina bearing minerals and the high viscosity of primary melts.
