Abstract

Abstract: Manganese leaching during high concentration flue gas desulfurization process with semi-oxidized manganese ore was studied in this paper. It was found that there were different reaction pathways among which MnO₂, Mn₂O₃ and MnCO₃ in semi-oxidized manganese ore during flue gas desulphurization and manganese leaching. High SO₂ concentration facilitated redox reaction between MnO₂ and SO₂, and high concentration of H₂SO₄ accelerated MnCO₃/Mn₂O₃ leaching from semi-oxidized ore. Kinetics study showed that manganese leaching in flue gas desulfurization process with semi-oxidized ore was controlled by a mixed-control model, that is the surface chemical reaction and mass diffusion dominated both the oxidation of SO₂ and manganese leaching process. The apparent activation energy was 13.05 kJ·mol^-1 and the reaction orders with respect to SO₂ and H₂SO₄ concentration were 1.38 and 0.10, respectively. Finally, a semi-empirical rate equation based on shrinking core model was derived to describe the process.
