Abstract
A bauxite of low quality containing 6.75% reactive silica and 37.4% Al2O3 as gibbsite was roasted with additives including NaOH (caustic/total alumina molar ratio of 2-4:1) and CaO (CaO/total SiO2 molar ratio of 0.5-3:1) at 300-1000 oC, producing calcines containing sodium aluminate (Na2O.Al2O3), silicates and hematite. Optimum conditions included roasting..... More
