Studies on the application of copper(I)-ammune sulphate electrolytes in copper electrorefining

Hydrometallurgy, 1982
Abstract The electrolysis of a copper(I)-ammine sulphate electrolyte between copper electrodes has been investigated. A sealed cell and a solution containing 30 g/kg Cu, 95 g/kg NH3 and 95 g/kg SO4 were used. Current efficiencies (cathodic and anodic), at current densities over 100 A/m2, were higher than 95% and were practically independent of the ...

Hypothesis about the origin of copper electrorefining slime

Hydrometallurgy, 1994
Abstract On the basis of microscopic observations of anode copper and copper electrorefining slime by secondary electron images, backscattered electron images, characteristic X-ray images and elementary analysis of specimens and using data from the literature about the constitution of binary and more complicated systems of Cu with the impurities in ...
