The treatment of copper refinery anode slimes SpringerLink

There are numerous viable approaches to the treatment of anode slimes from electrolytic copper refining. Of particular interest in the treatment of slimes are the behavior and recovery of selenium. The understanding of the process chemistry involved in the treatment of anode slimes should be aided considerably by recent work on the formation and characterization of slimes. Most promising is a

Processing of copper electrorefining anode slime: a review

2013-7-18  Abstract. Anode 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 to extract them following pyro

Passivation of Impure Copper Anodes

As the anode dissolves, some impurities report to the slimes and others to the electrolyte. Impurities in the electrolyte become concentrated over time in the closed electrolyte system. The studying of anode impurities has been limited to specially alloyed copper samples and a few commercial copper anodes.
