| description | The embodiment of the invention relates to the technical field of aluminum oxide production, in particular to a preparation process of ultralow-sodium aluminum oxide, industrial aluminum oxide is subjected to hydro-thermal treatment to prepare non-metallurgical-grade ultralow-sodium aluminum oxide, and the preparation process comprises the following steps: (1) introducing the industrial aluminum oxide prepared by roasting into a slurry tank with a stirring structure through a pneumatic chute, introducing water and acid, and uniformly stirring; (2) conveying the uniformly stirred slurry in the step (1) to a filtering flat plate through a slurry pump for suction filtration, and washing with weak filtrate and hot water; and (3) inputting the materials into a roller dryer to be dried. The embodiment of the invention has the beneficial effects that the non-metallurgical-grade ultralow-sodium alumina product with the sodium content of less than 0.05% is obtained by carrying out hydrothermal treatment on industrial |
