| Abstract: | The leaching function of high grade bauxite containing sulfur of Guizhou was studied.The effect of quantity of lime added,leaching-temperature,alkali-consistency and leaching-time on the yield of Al2O3 and the yield of sulfur were investigated.Meanwhile,the conditions and results of the desulphurizing were explored using the additive of Barium aluminate in the washable water of Baye pressure residues. |
| Keywords: | exploitable sulfur-containing and high grade bauxite baye pressure leaching function the washable water of baye pressure residues barium aluminates desulfurizing |
