Abstract
A method of operating a cell for electrowinning of copper, the cell including a plurality of anodes and cathodes therein, the method including the steps of introducing fresh electrolyte and sparging gas to a manifold system in the cell, controlling flow of fresh electrolyte and sparging gas in the manifold system and providing outlet openings in the manifold system such that streams of fresh electrolyte and sparging gas from the outlet openings are directed relatively uniformly across the cathodes in the cell.
