Abstract
Mineral carbonation processes have great potential for use as carbon capture and storage (CCS) technology. Mineral carbonation, using silicate rocks such as serpentinite, for the sequestration of CO2 through the formation of thermodynamic and environmentally stable products such as carbonates, presents itself as an economically efficient technology. This work presents a study on the leaching process of a serpentinite sample resistant to the leaching process. Experimental planning techniques were applied with the objective to optimize the process and maximize the Mg extraction of the serpentinite sample. The results show that as a result of the reduction of the sample size, a mechanical activation of the material occurred and the extraction of Mg was maximized.
