There are also several different companies that make separators specific for CU/Al that operate using "Electromagnetic Induction"

Flotation, if you can use a dense enough fluid. There are aqueous salt solutions with densities high enough to float aluminum, while letting copper sink. Some commercial vendors:

Recovery of the fluid for re-use is the catch here.
If not, then differential sink rates in a viscous fluid (you would need to process the scrap to get similar-sized particles).
Both technologies are probably best developed in mining applications.
