| Abstract Scope |
Red mud is an alkaline waste generated during alumina production. It has been stockpiled in large quantities due to the lack of technically and economically feasible treatment methods. TiO₂ sulfuric acid waste is an industrial sulfuric acid waste produced in the titanium dioxide manufacturing process, which also endangers the ecological environment. In this study, TiO₂ sulfuric acid waste was used to treat red mud, and the leaching behavior of Al, Si, Fe, and Ti components in red mud was investigated. Results show that under the conditions of 60 °C reaction temperature, 60 min reaction time, and a liquid-to-solid ratio of 6, TiO₂ sulfuric acid waste can selectively leach Al, Si, and Ti components from red mud, achieving efficient separation and comprehensive utilization of different components. This work provides important reference for the synergistic disposal of red mud and TiO₂ sulfuric acid waste. |
