These outcomes suggested that proper surface treatment of liberated copper foils with the conventional flotation reagents could be considered for their separation from Al. In the LIBs, Cu and Al are pure metallic foils; however, flotation of pure metallic copper and aluminum has rarely been investigated.
The sequential separation process started first with the delamination of anode films from copper foils in the buffer solution, followed by vortex shaking to reduce the size of the anode films. The resulting smaller anode films were separated from the copper foils and cathode pieces through sieving and filtration.
Various methods have been proposed for the separation of active materials (black mass) from metallic foils (copper and aluminum), one of which, that can also be applied on the industrial scale, is the mechanical–physical methods for the liberation of electrode materials from foils [ 36 ].
Whereas anode films can easily detach from copper foils in water, the delamination of cathode films does not exhibit the same behavior in water; instead, the cation exchange reaction results in lithium leaching and aluminum corrosion in the presence of water.
In this study, we present an aqueous separation technique, capable of sequentially isolating electrode/current collectors and anode/cathode components, thus enabling the recovery of anode films, cathode films, and metal foils in a streamlined one-pot system.
The delamination of spent anodes was performed in both deionized (DI) water and 0.1 M KH 2 PO 4 buffer solution, whereas the separation of cathode films from aluminum foils was conducted in the 0.1 M KH 2 PO 4 buffer solution with the addition of a certain volume of Triton™ X-100 surfactant.

Eddy Current Aluminium Separation
One interesting application is the selective sorting of various metals. Samples of mixed iron, aluminum, copper, lead, and zinc, sized at approximately 1 by ¼ inch were tested. While the iron was removed magnetically, an eddy-current separation of the aluminum and copper from the lead and zinc was established.
