Therefore, a series of aluminum recovery treatments are usually carried out on the waste aluminum ash. Currently, the recovery process for aluminum ash is usually to carry out hydrolysis treatment on the waste aluminum ash. A large amount of brine will be generated after the hydrolysis treatment of the waste aluminum ash. The brine will precipitate salt through an evaporator.
