contact us· Before the digestion, addition of 2.11% lime to the bauxite samples decreases the alumina recovery and increases the Na 2 O/SiO 2 ratio of red mud with increase in temperature. The highest alumina recovery and the lowest Na 2 O/SiO 2 ratio were achieved at 240 °C. It can be explained that lime partly reacts with silica in the bauxite and prevents sodium silicate formation [16, 17].
