“…The sample compositions were determined via an X-ray fluorescence spectrometer (XRF). Some phase equilibrium conditions commonly used in the reaction process can be obtained using FactSage thermodynamic simulation software, and the commonly used binary or ternary phase diagrams can also be obtained through this software, which can calculate the balance between solid products and gases in the P-CS calcination reaction system . For FactSage analysis, the temperature was changed from 100–1100 °C in 50 °C increments; the total pressure was 1 atm, the partial pressure of O 2 was 0.21 atm, and the Δ H of mineral reaction during P-CS calcination (100–700 °C) was calculated.…”

Calcium carbide slag (CS) is an industrial solid waste produced via the coal-based poly(vinyl chloride) process, and its main component is calcium hydroxide (Ca(OH) 2 ) (85−95 wt %). CS can be used instead of calcium carbonate (CaCO 3 ) to produce calcium oxide (CaO), reducing carbon dioxide (CO 2 ) emissions. Our group has reported that CaO can be prepared at lower temperatures using CS compared with existing processing temperature, where the calcination temperature decreases from 1000 to 700 °C when CaCO 3 is replaced with CS during CaO production. A comparison of the carbon emissions of CS and CaCO 3 -based CaO preparation processes show that using CS to produce CaO reduces CO 2 emissions by 977.62 kg/t. Herein, the CS-based CaO is explained by controlling the CS calcination temperature and mineral transformation. CS completely decomposes into CaO at 492 °C. The calcination temperature of CS is between 400 and 600 °C, where CaCO 3 is formed via the reaction of carbon and Ca(OH) 2 and water in CS. Furthermore, when the carbon content in CS is >4%, CaCO 3 is formed. When the calcination temperature is 700 °C, CaCO 3 decomposes into CaO. As the temperature increases, the metallurgical activity of CS increases, and its strength decreases. When the temperature is 700 °C, the compressive strength of CaO is 21.94 MPa, its metallurgical activity is 379.85 mL, and the CaO content is 95.14%. This study provides a new method for preparing CaO to simultaneously reduce carbon emissions and in-situ recycle CS.

“…Besides synthetic crystallization through the nucleation, crystal growth, and equilibrium stages, [49,50] there are also secondary processes such as agglomeration, aging, and maturation, all of which have significant impact on the morphology and structure of the product. Gen Ichiro Yamamoto [51] reported the structural modifications of magnesium carbonate hydrate throughout nucleation, crystallization, and thermal decomposition.…”

The increasing utilization of fossil fuels and industrial activities has resulted in a surge of CO2 emissions, which have significantly impacted global climate change. Carbon capture and utilization technologies offer a promising solution to decrease atmospheric CO2 concentrations and convert CO2 into valuable products. This study focuses on the capture and storage of CO2 through the mineralization of magnesium‐containing materials. The analysis encompasses the mineralization process of solid and liquid minerals, the various mineralization processes of magnesium‐containing minerals categorized as direct and indirect mineralization, and the latest research advancements in magnesium‐containing minerals. Brine and seawater from salt lakes are considered the most appropriate materials for mineralization due to their abundance and the simplicity of the process compared to solid mineralization. This paper analyzes the impact of temperature, impurity ions, additives, and microorganisms on the process of magnesium carbonate synthesis crystallization. The use of magnesium‐containing materials for carbon dioxide sequestration can effectively reduce carbon emission. The review offers guidance on carbon dioxide mineralization and explores the potential applications of magnesium mineralization.
