| Abstract: | The development of roughness at a rotating cylinder electrode has been investigated in the context of a metal recovery system — the ECO-CELL — where the solution concentration necessarily falls with time under batch processing. Roughness has been quantified using knurled cylinders and the use of thiourea as an additive has been considered. The development of a rough surface allows a reactor to recover metal at enhanced rates and the exploitation of this feature is discussed. |
