Desulfurization of Iron Ores: Processes and Challenges

Abstract. Various studies have been increasingly performed on the reduction of sulfur content of iron ores and concentrates. The presence of sulfur in these materials causes technical problems in steel and alloys and environmental issues in the sintering of iron ore process. The achievement of higher sulfur removal rates has been an important goal

Solid State Desulphurization of Iron Ore and Empirical

The possibility of dephosphorizing iron ore by breaking the phosphor-containing iron ore into granules of less than 0.074mm and then mixing it with iron pyrite pre-broken to the granules of less than 0.074mm based on mass percent of 5%-20% has been reported [1]. In this process, the mass

(OH)2 on the desulphurization. The mechanism of desulphurization of self- CaS03 becomes CaCO4 due to reaction with SO2 and finally it reacts with iron ore as follows, CaSO4 Fe203'= CaO Fez 03 SO2 + 40, (5) Therefore, it is considered that calcium fer-rite is formed and Sulphur . is removed as SO2 in

Mechanism of Selective Desulphurization in Iron Ore

01-02-2017· Iron ore sintering is an important part during the ironmaking process, and a large amount of SO 2 is also generated. Our previous research shows that it is an effective way to reduce SO 2 content of flue gas by adding urea to a special sintering material zone position. In this paper, the mechanism of selective desulphurization by adding urea during the iron ore sintering was carried out.
