| titleOfInvention | Modification method of alumina obtained by acid extraction of aluminium or fly ash acid extraction of aluminium and its application in the production of modified alumina and electrolytic aluminium |
| abstract | The invention relates to the field of electrolytic aluminum production of alumina obtained by acid extraction of aluminum, and discloses a modification method of alumina obtained by acid extraction of aluminum or fly ash acid extraction of alumina, modified alumina and application in the production of electrolytic aluminum . The modification method includes: (1a) crushing the alumina obtained by acid extraction of aluminum and then stirring it with aluminum sol or acid solution to form a slurry; or (1b) grinding the alumina obtained by acid extraction of aluminum with aluminum sol or acid solution (2) spray-drying the slurry to form spherical alumina particles; (3) calcining the spherical alumina particles to obtain modified alumina. The method solves the shortcomings of low bulk density, small particle strength and large repose angle of alumina obtained by acid extraction of aluminum, improves the current efficiency when it is used in electrolytic aluminum production, and can be directly used in electrolytic aluminum production. |
