Electrorefining - an overview | ScienceDirect Topics

Each anode is electrorefined until about 80%-85% of the mass has dissolved. Two or three cathode plating cycles are produced from a single anode. Each copper cathode typically weighs 50-160 kg. This multicathode plating cycle ensures that cathodes do not grow too close to the slime-covered anodes and become contaminated.
