| Abstract: | It is a study of the digesing characteristic of two representative Black-grey Bauxite-with high sulphur and no TOC and with high sulphur and TOC.We observe and study the digesing rate of sulphur,TOC and aluminum oxide and the influence of reaction temperature,concentration of caustic soda and addition of lime in order to develop the technology of wiping off the sulphur and TOC.And the study provides the original data to help the technology used in Bayer process directly. |
