Description

[0002] Alumina is a common industrial material. It can be used to make refractory materials, abrasives and polishing agents, ceramic materials, etc. It has broad application prospects. In the process of alumina raw material processing, impurity removal is an important link. When removing impurities, water-soluble impurities are usually carried out first to remove dust and impurities attached to the surface of alumina, so as to facilitate subsequent physical or chemical impurity removal.

[0003] In the prior art, when alumina is subjected to water-soluble impurity removal, it is generally poured directly into cleaning water, mixed and stirred so that impurities attached to its surface are dissolved in the cleaning water, and then filtered to obtain alumina, so as to achieve the effect of preliminary water-soluble impurity removal.
