10.07.2017· 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 low-grade iron ore has been processed. The fines resulting .
01.01.2012· As the raw materials available to produce fluxed pellets become more difficult, more attention is being paid to the use of hydrated lime in iron ore pelletizing. The authors conducted a study comparing bentonite and hydrated lime as binders for manufacturing fluxed pellets from a hematite pellet feed.
The effect of lime addition in hematite iron ore pelletson its physico-chemical as well as mechanical properties with respect to blast furnace requirement was studied in a laboratory scale with varying basicity i.e. 0-2.0.Increasing addition lime produced more calcium-alumino-silicate phases (slag)asevidenced by SEM-EDAX analysis. These phases have low melting points which enhances sticking ...
The addition of lime (CaO) to the iron ore fines slightly decreases the productivity of green pellets, but increases the drop resistance and the compressive strength of green pellets. Further the strength of the pellets is directly proportion with the shrinkage that takes place during firing of the pellets. In case of fluxed pellets, the addition of lime increases pellet shrinkage and hence ...
01.01.2015· Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction processes. The pelletization process is very widely used, .
