Efficient copper recovery from low-grade electric wire scraps using a low-cost mechanical process and low-cost materials

Upgrade of wire scrap by sieving and final copper recovery by chemical dissolution (cementation or electrowinning)

Copious quantities of chlorides inhibit cementation by means of aluminium, due to CuCl formation.

Pure Cu electrodeposition onto stainless steel cathode with Pb anode; reuse of electrolytic solution to dissolve Cu
