Experimental study on plagioclase dissolution rates at conditions relevant to mineral carbonation of seafloor basalts

Over the last two decades, all scenarios projected to achieve the goals of the Paris climate agreements have required negative emissions of greenhouse gases. Mineral carbonation of basalt is a promising negative emission technology for long-term storage of carbon dioxide (CO2). During mineral carbonation, dissolved CO2 is converted into solid carbonate minerals through reaction with silicate minerals. Plagioclase feldspars are the most abundant …
