The amount of Mg mobilized from tailings is sensitive to the etching conditions, as you nicely demonstrated. The partial pressure of CO2 seems to play a very important role (slide 6). At relatively low partial pressure of CO2 (such the atmospheric conditions), is the release of Mg sufficient to make feasible the carbon capture process in terms of yield (amount of product/amount of substrate)? Or is it most likely the use of CO2-concentrated gaseous mixture to enhance the reactivity of the substrate?
