Microbially induced calcium carbonate precipitation: a

11.05.2019· Le Métayer-Levrel et al. Mineral carbonation is achieved in a chemical process that CO 2 reacts with a metal oxide such as calcium to form carbonates. Carbonation has the potential to be an effective tool for capturing CO 2 as it is a single quick process, and, more importantly, it does not require any CO 2 transport which can substantially reduce the costs and risks of leakage. However
