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 a vertically-arranged series of horizontal bipolar cathodes in an electrolyzer assembly.
