摘　　要：电解铝在生产过程中产生了大量铝灰。若铝灰不经处理直接废弃,既污染环境又会给企业带来巨大经济损失。本文从铝行业发展循环经济、绿色经济的角度从发,介绍了从铝灰中回收铝的5种方法:炒灰法、倾动回转窑处理法、等离子电弧法、石墨电弧法、ALUREC法。Electrolytic aluminum produced a large number of aluminum dust in the production process,without direct waste not only pollute the environment but also brings economic losses.Based on the development of circular economy and green economy,this paper introduced five methods of recovering aluminum from aluminum ash:fried ash method,tilting rotary kiln treatment,plasma arc method,graphite arc method and ALUREC method.
