Abstract

Disclosed are solutions for the recovery of elemental metals at industrial scales without smelting including, for example, the recovery of near-pure lead from recycled LABs via specialized electrolytic processing. Further disclosed are new processes, innovative electrolyzer designs, and/or novel utilization of supplemental chemicals necessary for successful electrolysis of pure metal from impure forms (e.g., pure lead from lead oxides), and especially applicable for solid-state electrolysis of mixtures comprising lead paste, electrolyte, and supplemental chemicals. With particular regard to recovering near-pure lead during LAB recycling, solid-state electrolysis of mixtures comprising impure lead (e.g., lead paste) is made possible by electrolytic processing using supplemental chemicals, and made scalable to industrial levels via utilization of an horizontal cathode in the electrolyzer.
