A method of recovering metals from a source material (e.g. lithium battery waste) by adding acid to the source material, and then adding a reducing agent (e.g. a peroxide) to the leach solution while maintaining its temperature at 85 0C or less. While the acid and reducing agent are added, one of foaming, the rate of change of leach metal concentration in the solution, the rate of change of pH or the initial concentration of a leach metal is monitored. The addition of acid and reducing agent are respectively stopped when i) all target metals have been solubilised and the pH is between 0-2.3 and ii) the pH is between 1-2.3. A base is then added to increase the pH to 5 to 5.3 along with an oxidising agent (air or oxygen) to remove metals such as iron and aluminium. Metals can be recovered from the depleted leach solution. Apparatus for performing the method comprise a leach tank with an agitator and a foam breaker on a common shaft and a recirculation loop for spraying liquid from the tank onto foam in the tank.

A method and system for slitting a lithium-coated polyethylene terephthalate (PET) roll is provided. The roll undergoes laser ablation to remove a portion of a layer of lithium where a slit is desired exposing the PET substrate underneath. The roll then undergoes a blade cutting process wherein the roll is cut along exposed PET substrate, producing a plurality of slit rolls. The laser ablation of the roll prior to blade cutting allows lithium to be removed, preventing lithium build-up on the blade. This reduces maintenance time, improves the quality of the slit roll edges, and allows for longer lengths of rolls to be cut. The laser ablation also allows for rolls with thick layers of lithium to be blade cut.
