How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Mineral carbonation of alkaline mine residues is a carbon dioxide removal (CDR) strategy that can be employed by the mining industry. Here, we describe the mineralogy and reactivity of processed kimberlites and kimberlite ore from Venetia (South Africa) and Gahcho Kué (Canada) diamond mines, which are smectite-rich (2.3–44.1 wt.%). Whereas, serpent...
Mineral carbonation is a Carbon Capture Utilization and Storage (CCUS) technique that can be used to remove or divert carbon dioxide (CO2) from the atmosphere and store it in carbonate minerals. Hydraulic fracturing flowback and produced water (FPW) is Ca- and Mg-rich wastewater generated by the petroleum industry that can be used to sequester CO2...
Flowback and produced water (FPW) generated by hydraulic fracturing operations is highly saline and contains elevated concentration of ions including calcium and magnesium. Here, we investigate the use of FPW as a source of calcium and magnesium for carbon dioxide (CO2) capture and storage in carbonate minerals. We performed pH titration experiment...
Enhanced rock weathering (ERW) sequesters CO2 via solubility and mineral trapping and can be implemented by the mining industry to reduce their net greenhouse gas emissions. Kimberlite residues from Venetia Diamond Mine in South Africa, as well as powdered forsterite, serpentinite, wollastonite skarn, and 10 wt.% brucite mixed with quartz sand, wer...
Mineralogically complex feedstocks, including kimberlite, serpentinite, and wollastonite skarns, have vast capacities to sequester carbon dioxide (CO2) through enhanced rock weathering and CO2 mineralization. However, only a small reactive fraction of these feedstocks will be accessible for carbon dioxide removal at Earth’s surface conditions. We h...
Mineral carbonation is a negative emissions technology for capturing CO2 in carbonate minerals. Previous studies have demonstrated that accelerated production and carbonation of brucite [Mg(OH)2] from synthetic saline water can be used to store atmospheric CO2 in hydrated Mg- carbonate minerals [1,2]. In this study, we use hydraulic fracturing flow...
Mineral carbonation is one of the promising methods for CO2 sequestration and is part of a strategy for mining companies to offset their greenhouse gas emissions . In this study, we investigated the reactivity of kimberlite ore and processed kimberlite (tailings) from the Venetia and Voorspoed diamond mines (South Africa). Processed kimberlites...
