摘      要：Mineral carbonation is a promising CO_(2) sequestration strategy that can utilize industrial wastes to convert CO_(2) into high-value CaCO_(3).This review summarizes the advancements in CO_(2) mineralization using typical industrial wastes to prepare ultrafine CaCO_(3).This work surveys the mechanisms of CO_(2) mineralization using these wastes and its capacities to synthesize CaCO_(3),evaluates the effects of carbonation pathways and operating parameters on the preparation of CaCO_(3),analyzes the current industrial application status and economics of this *** to the large amount of impurities in solid wastes,the purity of CaCO_(3) prepared by indirect methods is greater than that prepared by direct *** CaCO_(3) includes three *** polymorph of CaCO_(3) synthesized by carbonation process is determined the combined effects of various *** parameters essentially impact the nucleation and growth of CaCO_(3) by altering the CO_(2) supersaturation in the reaction system and the surface energy of CaCO_(3) *** the initial pH of the solution and the CO_(2)flow rate favors the formation of vaterite,but calcite is formed under excessively high *** formation is favored at lower temperatures and residence *** increased temperature and prolonged residence time,it passes through aragonite metastable phase and eventually transforms into ***,polymorph modifiers can decrease the surface energy of CaCO_(3) grains,facilitating the synthesis of ***,the large-scale application of this technology still faces many problems,including high costs,high energy consumption,low calcium leaching rate,low carbonation efficiency,and low product ***,it is necessary to investigate ways to accelerate carbonation,optimize operating parameters,develop cost-effective agents,and understand the kinetics of CaCO_(3) nucleation and crystallization to obtain products with specific crystal ***
