The properties of iron ore sinter - commonly defined by measures of tumble strength, reduction degradation and reducibility - have a major impact on blast furnace performance. These properties are largely influenced by raw material properties, in particular the bulk ore composition. Despite this importance, there is a lack of quantitative data on the impact of ore chemical composition on iron ...

Many different approaches have been used in the past to characterise iron ore sinter mineralogy to predict sinter quality and elucidate the impacts of iron ore characteristics and process variables on the mechanisms of sintering. This paper compares the mineralogy of three sinter samples with binary basicities (mass ratio of CaO/SiO2) between 1.7 and 2.0.

Iron ore sinter is ideally composed of unreacted iron ore nuclei (~30 - 40 per cent) cemented together by a porous matrix (~60 - 70 per cent) comprising mainly complex ferrite phases (denoted by the acronym SFCA - silico-ferrite of calcium and aluminium) plus minor calcium silicates and glass. The sinter matrix forms largely from high-temperature reactions between the added fluxes and the ...

2015-1-1 In iron ore sinters, the presence of different phases reflects differences in sinter constituent mixtures and different temperatures and reductant additions during sintering. This can be of use in the development of stronger, more reducible sinters of the desired basicity. 3.7. Use of mass balancing in iron ore

Iron ore sinter is a complex composite material of ~40–70 wt% iron oxides (hematite, Fe 2 O 3, and magnetite, Fe 3 O 4), 20–50 wt% Ca-rich ferrite phases, up to 10 wt% glasses, and up to 10 wt% calcium silicates of which larnite, Ca 2 SiO 4, is the most common (Patrick and Lovel, Reference Patrick and Lovel 2001). Most of the Ca-rich ...

2018-12-13 The iron content of the ore depends on the relative proportion of iron-bearing minerals magnetite (Fe 3 O 4, 72.4 wt % Fe), hematite (Fe 2 O 3, 69.9 wt % Fe) and goethite (FeO(OH), 59.9 wt % Fe). Goethite has the highest amount of impurities and water, and water release during sintering increases porosity in the sinter (Pena et al., 2003).

2017-7-24 Luossavaara-Kiirunavaara AB (LKAB) operates one iron ore mine, three concentration plants and three pelletising plants in Kiruna, Sweden. The current methods of separation at the beneficiation plants are low intensity magnetic separation (LIMS) and reverse apatite flotation, where the wet LIMS stage is regarded as the crucial part of silica separation from the ore.

2018-7-11 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 ...
