wollastonite carbonate sulfuric acid

ESurf

When sulfuric acid reacts with carbonate minerals, dissolved inorganic carbon is added to ambient waters which leads to CO 2 release towards the atmosphere in the long term (Lerman et al., 2007; Calmels et al., 2007; Li et al., 2008; Torres et al., 2014). The relevance of this process for the global carbon cycle is two-fold.
