Composite agglomeration process (CAP) is an effective method to utilize the iron-bearing dusts generated in the ironmaking plants, by which the dust percentage in the sinter feed can be increased up to 20 wt %. In the current study, a comparison on behavior of iron-bearing dust in the conventional sintering process (CSP) and CAP was characterized. The results showed, in the CSP products, the scattered iron-bearing dust in the mixture was disadvantageous for the sintering indexes and consolidation of the finished sinters. In the CAP products, the main phase in the iron-bearing dust pellets was well-crystallized Fe2O3 grain particles. In the matrix parts, there were more Fe3O4 particles generated, which caused to high RDI+3.15 and low RI of the finished products. The pellets and the matrix parts were bonded by iron oxides and acicular calcium ferrite.
