Abstract Scope The calcification-carbonization process is attracting attention as a new, feasible method for clean production of alumina and treatment of red mud. The carbonization stage within the overall process was investigated, and the effects of CO2 concentration and pressure on the recovery of sodium oxide and alumina from red mud were studied in detail. The results showed that when the CO2 total pressure is 1.2 MPa and the CO2 concentration is 99.99%, the recovery of alumina and sodium oxide reached 40.08% and 93.16%, respectively. Similar results can also be achieved when the CO2 partial pressure is 1.2 MPa and the CO2 concentration is only 60%. And the main phase of solid slag is converted from hydrogarnet to CaCO3. This study aims to provide a theoretical basis for the industrialization of calcification-carbonization method.
