Abstract

Agitation of the electrolyte by gas sparging was studied as a means of intensifying the electrowinning of copper. Diffusion layer profiles at the cathode were quantitatively measured using a new technique based on the mass transfer controlled codeposition of a tracer metal ion. Smooth, good quality cathodes were produced in a prototype cell at current densities up to 30 A/dm2 (270 asf).
