Abstract

Abstract:

Aluminum dross is a harmful solid waste generated in the production process of aluminum industry,and the annual output reaches millions of tons.The massive accumulation of aluminum dross can cause serious environmental and public safety problems.The aluminum dross contains metal aluminum and its oxides and nitrides.Therefore,this is an great significance thing that comprehensive recycling of aluminum dross for reducing environmental pressure and improving the economic benefits of the aluminum industry.The pyrometallurgy and hydrometallurgy processes for aluminum dross were expounded.It was concluded that the salt-free technologies and the hydrometallurgical were more promising.The comprehensive utilization status and research progress of aluminum dross in the fields of refractory materials,ceramic products,hydrogen preparation and engineering materials were introduced.It was pointed out that while further consolidating and developing the original high value-added resource utilization,the utilization of gas generated in the process of aluminum dross treatment was strengthened,and it was suggested to further develop new resource utilization directions based on the characteristics of aluminum dross.

Key words: aluminum dross, solid waste, resource utilization
