| Abstract: | Making a brief introduction of the effect of lime on the pressure digestion of banxite by Bayer process,the Writers discuss in detail the lime's catalytical effect in digestion process.The catalytical mechanism and model have been established. Some kassite is found in the red mud,and its crystal parameters are determined.The chemical cause for the reduction of caustic soda losses is also analysized. |
