Summary: Field trials combining mined kimberlite material and mine derived microbes showed accelerated kimberlite weathering, potentially contributing to carbon sequestration. The addition of Fine Residue Deposit (FRD) kimberlite material enhanced microbial growth and weathering. The microbial inoculum and resulting geochemical changes promoted the transformation of kimberlite into a soil-like substrate capable of supporting plant growth.

Summary: Carbon capture and utilization (CCU) is a key pathway to reduce carbon emissions. This study focuses on the carbon abatement potential of a CO2 mineralization technology for CCU in Singapore, which converts CO2 into solid carbonates or sand using waste-to-energy plant emissions and serpentine mineral. Life cycle assessment (LCA) methodology was employed to analyze the net carbon emissions, showing that the technology abates 115.78 kg CO2-eq per tonne of CO2 input, with emissions mainly coming from transportation and activation processes. Possible strategies to enhance the carbon abatement potential include sourcing materials regionally and using renewable energy.

Summary: Ex situ aqueous mineral carbonation of ultramafic mining waste is a promising technology for CO2 sequestration, especially from small- to medium-scale emitters. The locally available ultramafic material shows potential for sequestering CO2 and producing aragonite and hydromagnesite as major products through aqueous mineral carbonation at ambient temperature. The method could potentially be integrated into existing mineral extraction and tailings management operations.

Summary: Mining waste has the potential to be used as essential feedstock for long-term carbon sequestration through a mineral carbonation process. The mineralogical and chemical composition of the waste, along with factors such as particle size, temperature, and pH, play a significant role in determining the efficiency of carbonation. Controlling these factors can lead to enhanced carbonation efficiency of the waste materials.

Summary: This study evaluated 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. The results showed that alkaline pH, smaller particle size, and low reaction temperature favored the carbonation process. Fe-rich mine waste exhibited a high potential to be utilized as feedstock for mineral carbonation, contributing to carbon sequestration and the production of value-added carbonate products.

Summary: Microbiological weathering of CRD kimberlite enhanced mineral carbonation. Photosynthetically enriched biofilm cultures mixed with kimberlite showed maximal carbonation conditions. Mineral carbonation also occurred in the dark and under water-saturated conditions. Microbial weathering produced calcium/magnesium carbonates on silicate grain boundaries and calcium/magnesium sulphate(s) under vadose conditions. The presence of bacteria was necessary for mineral carbonation, and the bacterial diversity in weathered kimberlite was consistent with soils and metal cycling.

Summary: The study discusses the option of reducing CO2 emissions in the cement industry by utilizing CO2-containing flue gas and cement kiln dust to produce mineral carbonates. Implementing the MCCKD process results in an increase in cost of goods and a decrease in CO2 emissions, especially in scenarios with full abatement. From an economic feasibility and environmental advantage perspective, the MCCKD process combined with renewable energy for transport and storage shows significant benefits compared to the same process based on fossil energy sources.

Summary: The utilization of cement byproducts to enhance carbon sequestration in concrete can contribute to cleaner production and reduce carbon emissions. This study evaluated the impact of cement kiln dust (CKD) on the carbon dioxide uptake characteristics of concrete mixtures and found that finer-grained CKD incorporated into mixtures with higher water-binder ratio and low or high CKD content had higher relative CO2 uptake. Additionally, it was found that 12-hour pre-ACC curing offered better carbon dioxide sequestration performance.

Summary: Mineral carbonation of alkaline mine residues is a carbon dioxide removal strategy that can be employed by the mining industry. This study examines the mineralogy and reactivity of kimberlites and kimberlite ore from diamond mines in South Africa and Canada, and finds that the smectite phase within these rocks is highly reactive and can be used as a source of magnesium and calcium for carbonation reactions. This research suggests that smectites could be used as an alternative to highly reactive minerals in the mineral carbonation process, including in tailings from smectite-rich sediment-hosted metal deposits and oil sands tailings.

Summary: Phosphorus is an essential element for life and its cycle in the ocean is closely connected with the carbon and oxygen cycles. The study of phosphate oxygen isotopes can provide insights into various reactions related to phosphorus. By analyzing carbonate fluorapatite samples from the Mesoproterozoic Era in North China, it was found that the oxygen isotope values were lower compared to modern samples, indicating a warmer climate during that time period and a potential reason for the scarcity of phosphorite.
