The Effect of Bismuth on Microstructure of the Cathodic Copper Deposition of Copper Electrorefining

Journal of Electrochemistry, 1997
The electrocrystal formation, crystal orientation and the chemical composition of the cathodic copper deposition in the presence of Bi3+ in the electrolyte of acidified CuSO4 are studies by scanning electron microscopy, X-ray diffraction, atomic absorption and EDAM. The results indicate that the Bi could′t deposit on cathode when copper electrolysed at

Energy Balances in the Electrorefining and Electrowinning of Copper

JOM, 1981
Using basic heat transfer correlations, the distribution of heat losses in a copper electrorefining tank house has been determined. The initial study led to programs to cover refining cells at both Kennecott refineries, with potential energy savings of approximately 1 MM Btu/ ton cathode.

Current density optimization in the copper electrorefining process

Journal of Applied Electrochemistry, 1978
The way of estimating the costs of the electrorefining of copper and of selecting the optimum electrolysis current density has been presented. The analysis has been carried out for the flow electrolyser taking into account the capital costs, electrical energy costs, heating or cooling costs and the electrolyte pumping costs. Against a background of the

Microscopic examination of copper electrorefining slimes

Hydrometallurgy, 1990
Abstract Anodic and floating slimes from the copper electrorefining process were investigated by a microscopic method, supplemented with X-ray diffraction and sedimentation analyses data. The specific gravities and granulometric compositions of the slimes were established. The shape, surface roughness, dimensions of the particles and their structure

Reliability Evaluation of Sampling Electrorefined Copper Cathodes

1984
The reliability of routine cathode sampling procedure at Nassau Recycle Corporation was evaluated. The evaluation was conducted on both in-house and supplier's cathodes. Sampled cathodes were charged into the shaft furnace to make continuous cast wire rod, and the analyses of the cathodes and the rod from the same batch were compared.

Minor elements in copper smelting and electrorefining

2001
Minor element (As, Sb, Bi, Pb, Ni) behavior, control and removal techniques in the conventional copper smelting/electrorefining process was studied. The analysis was based on the information collected from an exhaustive literature review, the visit of 23 smelters, 14 electrorefineries and consultations at 15 different institutes specialized in the ...

BEHAVIOUR OF ANTIMONY AND BISMUTH IN COPPER ELECTROREFINING CIRCUITS

Canadian Metallurgical Quarterly, 2008
Antimony- and bismuth-rich copper anodes, anode slimes and decopperized anode slimes from industrial copper electrorefineries were studied mineralogically.

A study of anodic slime behaviour in the electrorefining of copper

Hydrometallurgy, 1995
Abstract The kinetics of anode slime formation and propagation were studied in a laboratory-scale copper electrorefining apparatus. Laser-based illumination and digital image processing of videotaped records of slime movement, combined with current/time monitoring and polarization experiments, provide quantitative information about the complex ...

Processing of copper electrorefining anode slime: a review

Mineral Processing and Extractive Metallurgy, 2009
AbstractAnode slime is the insoluble product deposited at the bottom of the electrorefining tank during electrorefining of copper. It generally contains Cu, Ni, Se, Te, Ag, Au, platinum group metals (PGM), Pb, Ba, Fe, etc. Owing to the presence of valuable metals and metalloids in the anode slime, numerous approaches have been made by the researchers ...
