Abstract
The increase in energy demand by this company is responsible for the release of (GHG) into the atmosphere. In order to mitigate these emissions, proposals have been disseminated to continue the use of traditional fuels, without interfering in the worldwide warming. Among these proposals, Carbon Capture and Storage (CCS) technologies play an essential role in mitigating CO2 emissions in the atmosphere. These consist of the separation of CO2 from anthropogenic activities. Mineral carbonation is classified as one of the CCS technologies, in which it is a technology based on the natural process of CO2 sequestration, known as the disintegration of the rocks, generating thermodynamic and environmentally stable products. This study aimed to evaluate the influence of granulometry on the leaching process of indirect mineral carbonation of a Brazilian serpentinite, in order to compare the extraction efficiency of the elements of interest (Mg and Fe). Based on the analysis of the experimental results, it was observed that although the SB sample was mechanically activated, there was no significant increase in the efficiency of Mg extraction indicating that the SM sample is the most viable to be used.
