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

Publicada en por admin

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[…]

Thermal characterization of new fire-insulating materials from industrial inorganic TiO2 wastes

Publicada en por admin

Abstract Two wastes, red gypsum (RG) and unattacked ilmenite (known as tionite), from the titanium dioxide production industry have been used to study the possibility of manufacturing new fire-isolating materials, and for that they were characterized for mineralogical composition and thermal behavior. Tests have demonstrated that these wastes could be used for fire insulation. Thermogravimetry Read more about Thermal characterization of new fire-insulating materials from industrial inorganic TiO2 wastes[…]

Physicochemical characterization of raw materials and co-products from the titanium dioxide industry

Publicada en por admin

Abstract The present study was conducted to characterize several raw materials and co-products from the titanium dioxide industry in relation to their elemental composition (major, minor and trace elements), granulometry, mineralogy, microscopic morphology and physical composition. The main objective was to gain basic information for the future potential application of these co-products in fields such Read more about Physicochemical characterization of raw materials and co-products from the titanium dioxide industry[…]
