In case of chromite, the temperature required for sintering is about 200 0 C more than that required for iron ore sintering. The process conditions for manganese ore sintering are almost similar to that for iron ore. The author has actively contributed to projects for setting up of batch type (capacity 15000 tpa) sinter plants at industry site.

The present work proposes a novel process to sinter porous iron ore (porosity ~23–24%) with enhanced productivity and quality. The iron ore is pre-processed in the presence of calcined lime for the temporary closure of pores, which further prevents water absorption during the granulation process in drum in the presence of water. The …

The iron ore in the sintering dust was mainly magnetite, a small amount of hematite and gangue. Moreover, a small amount of quicklime also existed in the sintering dust due to using it as a solvent for the sintering process (Wu et al., 2022b). The peak intensity of metallic iron rose with the temperature, while peaks of magnetite and …

Iron ore sintering is an important channel to utilize C-bearing dust, but the poor surface activity worsens the permeability of the green bed and reduces the yield and quality indexes of sinters. Thus, the C-bearing dust dosage should be within 5% during iron ore sintering process (Gan et al., 2018).
