Abstract
Disclosed are solutions for the recovery of elemental metals from dross at industrial scales without smelting including, for example, the recovery of near-pure lead from dross resulting from recycled lead-acid batteries (LABs) whether by smelting, electrolytic processing, or some other process. 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 monoxide) found in dross, and especially applicable for solid-state electrolysis of mixtures comprising lead dross paste, electrolyte, and supplemental chemicals. Solid-state electrolysis of mixtures comprising impure lead dross (e.g., dross paste) is made possible by electrolytic processing using supplemental chemicals, and made scalable to industrial levels via utilization of a horizontal cathode in the electrolyzer.
