In Bayer processBayer process, during digestionDigestion, reactive silicaSilica present in bauxiteBauxite dissolves and reacts with caustic soda to form sodalite. Formation of sodalite affects process efficiency and operational costs. It also contributes to scaling in equipment, increased bauxite residueBauxite residue generation, and heightened liquorLiquor viscosity, all of which hinder process performance and product qualityQuality. Conventional methods like increase in residence time in predesilication, addition of lime, reduction in target A/C, and increase in digestionDigestion temperature and time improved the desilication efficiency. However, the effects observed are not very consistent when the liquorLiquor causticityCausticity is high at ~95%. In this study, as innovative approach to control liquorLiquor silicaSilica level in liquorLiquor is attempted by reducing liquorLiquor causticityCausticity to ~89% with the addition of carbonate to Bayer liquorLiquor. The result indicated a significant drop in liquorLiquor silicaSilica ratio from 1.43 to 1.27 which helps in controlling silicaSilica impurities and scaling in the process.
