The symbiotic manganese oxides ore was applied to remove sulfur dioxide from flue gas. The desulfurization performance and mechanism of symbiotic manganese oxides ore was studied. The effects of ore particle size, reaction temperature, liquid-solid ratio, inlet gas flow and SO_2 inlet concentration on the desulfurization efficiency were determined.The results showed that the symbiotic manganese oxides ore include mainly MnO_2, Mn_2 O_3, MnCO_3, and there are mainly four processes for desulfurization: the ox...
