THE ISA PROCESS AND ITS CONTRIBUTION TO …

The Electrorefining Process Electrorefining of copper consists of electrolytically dissolving copper from impure anodes of about 99.7% copper, and selectively plating the dissolved copper in pure form onto the copper cathode. This reaction takes place in a cell containing anelectrolyte which is basically copper sulphate and sulphuric acid.
