Recovery of nickel powder from copper bleed electrolyte of an Indian copper smelter by electrolysis

Powder Technology, 2007
Abstract When nickel concentration increases in the copper sulphate electrolyte during electrolysis, it starts electrodepositing on the copper cathode thereby affecting the purity of the copper. In order to produce high quality copper cathodes with less than 1 ppm Ni, it became necessary to bleed-off large volumes of foul electrolyte contaminated ...

The Effect of Reversing Current on the Properties of Copper and Electrolytic Copper Powder. II. The Apparent Density and Flowability of Powders

Materials Science Forum, 2004
The apparent density and flowability of copper powder are related to the structure of powder particles and the reversing current (RC) regimes. It was shown that the apparent density of the powders increases with the increase in the compactness of particles, hence with the increase in the frequency of RC and with the decrease in the cathodic to anodic ...

Influence of antimony impurities in electrolyte on the electrodeposition of copper powder

Soviet Powder Metallurgy and Metal Ceramics, 1967
1. In the presence of antimony compounds in electrolyte, antimony is codeposited on the cathode, which promotes the oxidation of the copper powder. 2. Small amounts (up to 0.5–1.0 mg·eq/liter) of antimony impurity in electrolyte favor the formation of loose deposits with a strongly developed dendritic particle structure, while larger ...
