| Abstract: | After the process of digestion of sulfur-rich bauxite,the iron contents of pregnant liquor and alumina in Bayer process will be highly increased.After the temperature reducing and filtration of green liquor and pregnant liquor with high iron content,the iron content in the liquor will be significantly reduced,meanwhile,the iron content in alumina after precipitation with this liquor will be greatly decreased. |
