Industrial solid waste electrolytic manganese residue mineralization CO2 resource utilization method
The invention provides an industrial solid waste electrolytic manganese residue mineralization CO2 resource utilization method, which comprises: placing a mixture of electrolytic manganese residue and alkaline waste residue in a first container, adding water, and stirring to obtain ammonia gas and slurry; secondly, introducing ammonia gas into a second container filled with water, and introducing industrial tail gas containing CO2 into the second container to obtain an ammonium carbonate solution; carrying out solid-liquid separation on the slurry to obtain modified manganese slag; thirdly, mixing the ammonium carbonate solution with the electrolytic manganese residues to prepare calcium carbonate and ammonium sulfate; carrying out filter pressing on the modified manganese slag to obtain a modified manganese slag cake and alkaline wastewater; finally, introducing the alkaline wastewater into a first container; and drying and grinding the modified manganese slag cake to obtain the basic sulfate composite exciting agent. According to the method, efficient and gradient utilization of the electrolytic manganese residues is achieved, high-added-value utilization of the electrolytic manganese residues is achieved, the mineralized CO2 treatment cost is reduced, and the method has good application prospects and popularization value and has important significance in achieving carbon peak reaching and carbon neutralization.
