Description

Technical Field

[0001] The present invention relates to the technical field of aluminum ash recovery, in particular to a production process for recovering metallic aluminum from aluminum ash. Background Art

[0002] Aluminum smelting and forming processes generate a variety of byproducts. Aluminum ash, a major byproduct of the aluminum industry, is produced throughout all aluminum melting processes. The aluminum content in this ash accounts for approximately 1-12% of the total aluminum losses during production and use. Traditionally, aluminum slag has been discarded as waste, a practice that not only wastes aluminum resources but also creates environmental problems. Therefore, finding cost-effective methods to utilize and manage aluminum slag will not only improve the economic benefits of the aluminum industry and effectively recycle resources, but also have a significant impact on achieving sustainable economic and social development.

[0003] Most of the existing methods for recovering metallic aluminum from aluminum ash slag are to first crush the aluminum ash slag through a crushing device, then pour it into a screening device after crushing to screen out the impurities in the aluminum ash slag, and then separate and refine some of the aluminum. Crushing equipment or screening equipment cannot have the functions of screening or crushing at the same time, making the operation steps more cumbersome. For this reason, we propose a production process for recovering metallic aluminum from aluminum ash slag. Summary of the Invention
