“…The ultramafic rock-hosted ore deposits that are favored for integrated mineral carbonation technologies include chrysotile [63], nickel [64][65][66], chromium [67,68], diamond [69] and platinum group element (PGE) mines [70,71]. These mine types are abundant worldwide and their CO 2 storage potential is large [61].…”

Recently, integrated mineral carbonation for CO 2 sequestration has received significant attention due to the high potential for commercialization towards mitigating climate change. This review compiles the work conducted by various researchers over the last few years on integrated mineral carbonation processes in the mining industry, which use ultramafic mine wastes as feedstock for mineral carbonation. Here, we introduce the basic concepts of mineral carbonation including a brief description of the process routes and pre-treatment techniques. We discuss the scope of integrated mineral carbonation process application, and critically review the integrated mineral carbonation process in the mining industry including modified passive carbonation techniques in tailing storage facilities, and ex-situ carbonation routes using fresh tailings. The focus of the discussions is the role of reaction condition on the carbonation efficiency of mine waste with various mineralogical compositions, and the benefits and drawbacks of each integrated mineral carbonation process. All discussions lead to suggestions for the technological improvement of integrated mineral carbonation. Finally, we review the techno-economic assessments on existing integrated mineral carbonation technologies. Research to date indicates that value-added by-products will play an important role in the commercialization of an integrated mineral carbonation process.

Mineralization of Carbon Dioxide: A Literature Review

Research on carbon capture and storage has been focused on CO 2 storage in geologic formations, with many potential risks. An alternative to conventional geologic storage is carbon mineralization, where CO 2 is reacted with metal cations to form carbonate minerals. Mineralization methods can be broadly divided into two categories: in situ and ex situ. In situ mineralization, or mineral trapping, is a component of underground geologic sequestration, in which a portion of the injected CO 2 reacts with alkaline rock present in the target formation to form solid carbonate species. In ex situ mineralization, the carbonation reaction occurs above ground, within a separate reactor or industrial process. This literature review is meant to provide an update on the current status of research on CO 2 mineralization.

“…Rates of conversion to a carbonate product from 24% to 74% were achieved through the reduction of particle size from <2 mm to <38 µm in 30 min of reaction time (19 bar and 100 • C) [74]. Accordingly, the surface area can be increased by grinding or sieving, making the particle size smaller but with more available surface area for the reaction to occur; this is also known as mechanical activation [24]. Although the uptake capacity obtained through this experiment was quite low, the results were comparable to that of using a high-energy reactor (high pressure and high-temperature system).…”

“…CCS transfers the captured carbon dioxide to a chosen storage area for a long period of time, while CCU converts the captured carbon dioxide into a value-added product that can bring revenue to various sectors, such as bendable concrete, methane, urea and fuels [7,8,[14][15][16][17][18][19][20][21][22]. Out of these potential CCS and CCU technologies, mineral carbonation has been suggested as an ideal approach where the carbon dioxide in the atmosphere can be stored and kept permanently as a stable and non-toxic carbonate product that can further be used and commercialized (e.g., partial cement replacement, brick production, paint and many more possibilities) [23][24][25]. This shows that mineral carbonation can act as a useful approach for both CCS and CCU, but the latter seems more promising, as it offers additional revenue in addition to removing carbon dioxide from the air.…”

CO2 Sequestration through Mineral Carbonation: Effect of Different Parameters on Carbonation of Fe-Rich Mine Waste Materials

Mineral carbonation is an increasingly popular method for carbon capture and storage that resembles the natural weathering process of alkaline-earth oxides for carbon dioxide removal into stable carbonates. This study aims to evaluate the potential of reusing Fe-rich mine waste for carbon sequestration by assessing the influence of pH condition, particle size fraction and reaction temperature on the carbonation reaction. A carbonation experiment was performed in a stainless steel reactor at ambient pressure and at a low temperature. The results indicated that the alkaline pH of waste samples was suitable for undergoing the carbonation process. Mineralogical analysis confirmed the presence of essential minerals for carbonation, i.e., magnetite, wollastonite, anorthite and diopside. The chemical composition exhibited the presence of iron and calcium oxides (39.58–62.95%) in wastes, indicating high possibilities for carbon sequestration. Analysis of the carbon uptake capacity revealed that at alkaline pH (8–12), 81.7–87.6 g CO2/kg of waste were sequestered. Furthermore, a particle size of <38 µm resulted in 83.8 g CO2/kg being sequestered from Fe-rich waste, suggesting that smaller particle sizes highly favor the carbonation process. Moreover, 56.1 g CO2/kg of uptake capacity was achieved under a low reaction temperature of 80 °C. These findings have demonstrated that Fe-rich mine waste has a high potential to be utilized as feedstock for mineral carbonation. Therefore, Fe-rich mine waste can be regarded as a valuable resource for carbon sinking while producing a value-added carbonate product. This is in line with the sustainable development goals regarding combating global climate change through a sustainable low-carbon industry and economy that can accelerate the reduction of carbon dioxide emissions.
