摘要：
The aqueous mineral carbonation process that leaching alkaline earth metals from industrial residues by ammonium salt and carbonation thereafter is one of the potential technologies for CO2 sequestration. In this paper, the effect of particle size of waste slag on the leaching rate of metals under a microwave field and effect of microwave irradiation on the carbonation process were investigated. It was found that the initial leaching ratio of Ca decline seriously with the particle size of EAF slag increasing, and the Ca leaching ratio is relatively low during 120 min leaching. The lower leaching ratio of Ca with large particle size is due to the existence of a silica product layer produced on the surface of calcium silicates. Moreover, due to the microwave irradiation, the leaching ratio of calcium and the crystallization rate of calcium carbonate increase, though the particle size and distribution range of calcium carbonate reduce.
