The iron ore concentrate is mixed with carbon, and fed into a rotary kiln, where the material is tumbled at 62 Iron Ores and Iron Oxide Materials. high temperature to form nodules [8]. Reached temperature is enough to soften the ore but not to fuse it. Problems of the nodules are the considerable differences in composition and density

Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make iron ore concentrate …

Similarly, Nyembwe et al. [23] reported that a partial replacement of iron ore fines by concentrate and micropellets results in a complex granulation mechanism. It was found that the incorporation of concentrate and micropellets in sinter feeds produce granules with smaller Sauter mean diameter [23].

The compactness (density) of the ore concentrate was found to have very little effect on pXRF readings. The pXRF readings for Fe and Si were comparative to laboratory-based XRF results. Based on the strong correlations between the pXRF and XRF results (Fe: R 2 > 0.99, Si: R 2 > 0.96), linear calibrations were adopted to improve the accuracy of ...

The portion of −20 µm in iron ore concentrate favoured the granulation and the productivity in conventional sintering, but the portion of +45 µm had the reverse effects. With increases in finer commercial concentrates (10–40 mass%) combined with low grade ore (10–20 mass%) in iron ore blends, the productivity also did not obviously change.

Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …
