Recent advances in copper electrowinning [electronic resource] / D. J. MacKinnon and V. I. Lakshmanan. [Ottawa] : Mineral Research Laboratories, 1976. iv, 53 p. CANMET report ; 76-10E Cover title. "January 1976." Includes bibliographic references. "The application of solvent extraction techniques to copper leach liquors has resulted in a great deal of basic research designed to improve the copper electrowinning stage. The main objective of this research is to increase the current density, and therefore the rate at which copper is deposited in both refining and winning cells. This review details the methods currently being practised to achieve high current density in copper winning cells and the consequent effects on various aspects of the electrowinning process. New cells designed for electrowinning copper from dilute solutions are also discussed. The effect of impurities and addition agents on the growth and morphology of copper is reviewed in detail"--Abstract, p. i.
