Electrowinning circuits normally use a number of additives in the electrolyte to promote smooth, compact deposits. These cathodes have the best levels of purity. When electrowinning is coupled to a solvent extraction operation, it is important to minimize the amount of surface-active additives used, as their presence tends to increase phase-disengagement times.

An improved electrolyte circulation manifold system for use in a copper electrowinning cell which includes an array of alternating cathode and anode plates positioned within a holding tank is disclosed. The manifold system itself includes a first manifold section positioned within the holding tank adjacent to a first lateral edge portion of each cathode plate and anode plate in the array.
