Conference Paper Description

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 CO concentration and pressure on the recovery of sodium oxide and alumina from red mud were studied in detail. The results showed that when the CO total pressure is 1.2 MPa and the CO 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 CO partial pressure is 1.2 MPa and the CO concentration is only 60%. And the main phase of solid slag is converted from hydrogarnet to CaCO. This study aims to provide a theoretical basis for the industrialization of calcification-carbonization method.
