Ore sintering flue gas desulfurization and its

Flue gas desulfurization (FGD) has been implemented for sulfur dioxide gas emission reduction by pyrolusite in iron ore sintering. However, the mechanism of SO 2 reduction through FGD is still not fully clear. And in present work, the effects of operating conditions on desulfurization rate and Mn 2+ leaching rate of pyrolusite were investigated.
