Method for harmlessly treating and recycling aluminum ash
The invention discloses a method for harmlessly treating and recycling aluminum ash, and belongs to the technical field of comprehensive utilization of waste resources in the aluminum industry. The invention provides a method for harmlessly treating and recycling aluminum ash. The method comprises the following steps of: S1, primary dry grinding for aluminum extraction; S2, secondary dry grinding for aluminum extraction; S3, deamination; S4, wet grinding and sorting; and S5, fluorine fixation treatment. According to the method for harmlessly treating and recycling aluminum ash, components harmful to the environment in the aluminum ash can be extracted or solidified, harm to the environment is reduced and avoided, the recovery rate of effective components in the aluminum ash is high, the recycling range of the aluminum ash is widened, and meanwhile energy consumption is reduced.
本发明公开了一种铝灰无害化处理并回收利用的方法，涉及铝工业废弃资源综合利用技术领域。本发明提供的一种铝灰无害化处理并回收利用的方法，包括以下步骤：S1.一次干磨提铝；S2.二次干磨提铝：S3.脱氨；S4.湿磨分选；S5.固氟处理。本发明提供的一种铝灰无害化处理并回收利用的方法，能够将铝灰中对环境有害的成分提取或固化，降低和避免了对环境的危害，铝灰中有效成分的回收率高，扩大了铝灰回收利用范围，同时降低了能耗。
