Composite agglomeration process (CAP) of iron ore fines has been proved an effective route for ironmaking burden production, and is characterized by low the fuel consumption and high the productivity compared with the traditional sintering process. Sintering behavior of pelletizing feed in CAP has not been studied fully yet.

Apr 02, 2010 Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation. As shown in Figure 14.1, iron ore sintering is carried out in three stages: raw material ...

Jun 11, 2019 Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It’s a major ingredient in steel.

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...
