Potential of Tailing Deposits in Chile for the Sequestration of Carbon Dioxide Produced by Power Plants Using Ex-Situ Mineral Carbonation
In this study, the potential of copper tailing deposits in Chile for the sequestration of carbon dioxide (CO<sub>2</sub>) via ex-situ mineral carbonation integrating the recovery of valuable metals was assessed. An inventory of tailing deposits and CO<sub>2</sub> sources exis...

| description | In this study, the potential of copper tailing deposits in Chile for the sequestration of carbon dioxide (CO<sub>2</sub>) via ex-situ mineral carbonation integrating the recovery of valuable metals was assessed. An inventory of tailing deposits and CO<sub>2</sub> sources existing in Chile was constructed to determine the most suitable site for the installation of a future mineral carbonation plant and to evaluate the technical, economic, and environmental feasibility of CO<sub>2</sub> capture, separation, and transport from the source to the mineral carbonation plant. The data of the inventory of tailings deposits in Chile were obtained from the National Service of Geology and Mining. For the thermoelectric plants installed in Chile, data of energy production were obtained from the Energy National Commission. Through the use of the technique for order preference by similarity to ideal solution (TOPSIS) method and sensitivity analysis, the optimum location in the region of Antofagasta to install a mineral carbonation plant was identified. In addition, the results show that in the region of Antofagasta five tailing deposits have the potential to sequester between 66 to 99 Mt of CO<sub>2</sub>. Meanwhile, thermoelectric plants in 2018 produced about 9.4 Mt of CO<sub>2</sub> that is available to be sequestered, with a maximum generation potential of 21.9 Mt of CO<sub>2eq</sub> per year. The methodology and the study presented can be considered as a preliminary study to identify tailings that require further analysis. |
