The invention discloses a method for producing aluminium alloy ingots from abandoned pop cans. The method is characterized by comprising the following technological steps: (1) crushing: abandoned pop cans are crushed to particles of 300-500 micron meshes; (2) cleaning; (3) depainting; (4) smelting and deslagging; (5) grain refinement; (6) degassing; and (7) ingot casting. The technology is reasonable and concise. Technological flow is greatly shortened. As abandoned pop cans are used as a technological raw material, waste materials are changed into valuable things, and environment pollution caused by depainting in the technology is minimized. By the method, quality of aluminium alloy ingots is raised, and reutilization rate of aluminium is enhanced. The method provided by the invention has a wide market prospect.
