A laboratory-scale study of the aqueous mineral carbonation of coal fly ash for CO2 sequestration

Mineral sequestration of waste materials provides a promising method for CO2 sequestration, due to its potential as a finishing step in industries which produce CO2 and alkaline solid by-products. However, a number of challenges in mineral carbonation that remain to be resolved, including overcoming the slow kinetics of mineral–fluid reactions, dealing with the large volume of source material required, and reducing the energy needed to hasten...
