CO₂ Mineralization Technologies Across Industrial and Geological Settings: Trends and Advances
摘要
Carbon emission reduction is closely tied to mining and processing utilization, with mining engineering being one of the key sources of carbon emissions, offering significant potential for emission reduction. Carbon dioxide mineralization technology is an effective form of carbon capture and storage (CCS). The global application of mineralization technology is reviewed in this paper, with a focus on how the effectiveness of the technology is influenced by mineral resources, geographic location, and industrial context. Several technological pathways to achieve large-scale carbon emission reductions are also proposed. Calcium- and magnesium-rich minerals are ideal candidates for mineralization due to their high reactivity and abundant reserves. In high-temperature, high-pressure geothermal areas, the mineralization reaction is accelerated, facilitating traditional in situ mineralization projects. In resource-poor regions, innovative approaches, such as utilizing minerals with mineralization potential in sedimentary reservoirs, are required. Cold regions have explored the possibility of converting CO₂ into solid hydrates for storage. Industrial waste, particularly from traditional high-emission industries, represents a valuable resource for mineralization, as it can react with CO₂ emissions to achieve carbon sequestration while simultaneously promoting waste recycling. In addition, the mineralization potential of other types of industrial waste has been increasingly recognized, demonstrating considerable promise for future applications.
