摘　　要：Carbon dioxide (CO2) is a substantial contributor to global warming owing to its long atmospheric lifetime and high potential for global warming. It is related to the processes of raw material mining and industry, which is fundamental to economic development but also has negative impacts on the environment, namely the increase of global temperature and solid waste. To address this, various carbon capture, storage, utilization, and mineralization methods have emerged, but they remain at an early stage of development. This review discusses the applicability of solid waste materials, and slurry form in particular, for CO2 mineralization. It analyzes frequently researched materials, carbonation capabilities, reaction mechanisms, and industrial uses. Industrial waste materials, cement, and demolition waste are widely used in carbonation reactions because of their abundance and high Ca/Mg oxide content. The review also discusses carbonation types, including two major types—direct and indirect—which fall under the ex-situ category. The key factors influencing the carbonation efficiency include the CO2 concentration, temperature, pressure, particle size, and reaction chamber type. The construction sector is the principal beneficiary of carbonated materials due to the cementitious characteristics of recarbonated byproducts and precipitated calcium carbonate (PCC). Other industries, such as paper, plastics, and pharmaceuticals, also find applications for PCC. Future research is recommended to explore new materials for slurry carbonation, with potential applications in underground mine support for carbon sequestration and subsidence control.Carbon dioxide (CO2) is a substantial contributor to global warming owing to its long atmospheric lifetime and high potential for global warming.
