Application of Tricalcium Aluminate Instead of Lime for the Recovery of Aluminum in Middle-Low Grade in the form of low-concentration sodium aluminate solution which is comparatively difficult to reuse. In this paper, the low-concentration sodium aluminate solution was reused to prepare tricalcium aluminate and went back to the Calcification-Carbonization process instead of lime. When processing g

Low Temperature Reduction of Hematite in Red-Mud to Magnetite0 m%) was reduced to magnetite employing a gas based mixture of CO, CO. and N. as a diluent. Extensive thermodynamic study was conducted to identify the stability region for magnetite. ‘Optimal conditions’ for the gas-phase reduction were determined to be: a . of 540 °C ± 10 °C, . CO. and CO. each o

Processing Diasporic Red Mud by the Calcification-Carbonation Methodatch experiments were performed to evaluate the potential effects of important parameters such as temperature, amount of CaO added, CO. partial pressure and carbonation cycles on the recovery of alkali and alumina. The results showed that 78.74% alumina was recovered from the diasporic red mud with

Characterization of Activated Alumina Production via Spray Pyrolysisined by spray pyrolysis in tube furnace with aluminum chloride solution as raw materials in different temperatures. X-ray diffraction (XRD), scanning electron microscope(SEM) and the specific surface area analysis were used to characterize the spray pyrolysis products, respectively. XRD results show
