Abstract: Disclosed is a system for electrolytic processing or recovery of a metal from an electrolyte solution. The system may comprise electrolysis cells and a rectifier. The cells may comprise interleaved anodes and cathodes. The anodes or the cathodes of a first cell may have an electrical connection to a terminal of the rectifier, respectively, via a first electrical path having a first resistance. The anodes or the cathodes of a second cell may have an electrical connection to a terminal of the rectifier, respectively, via a second electrical path having a second resistance. The second resistance is configured to be higher than the first resistance. The system may further comprise a channel for electrolyte from the first cell to the second cell, the electrolyte containing the metal in a dissolved ionic form, metal concentration in the first cell being higher than in the second cell.
