CO2 sequestration by indirect carbonation of artificial gypsum generated in the manufacture of titanium dioxide pigments

Abstract In this paper, the use of red gypsum (RG), waste from the naturally occurring radioactive materials industry that is devoted to the production of the TiO2pigment, was evaluated as a source of calcium for CO2 sequestration by an indirect carbonation process. The main objective was to valorise this waste and, at the same time, Read more about CO2 sequestration by indirect carbonation of artificial gypsum generated in the manufacture of titanium dioxide pigments[…]
