The copper(II) ions are removed again from the organic solvent by reaction with fresh sulfuric acid, producing a much more concentrated copper(II) sulfate solution than before. Electrolysis of the new solution. Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below).

Extraction of Metals. The History of Metals.. Metals have been used by people for many thousands of years. Gold and silver, found as native metal, were used both as jewellery and as a status symbol - nothing new there. These metals were known in the Stone Age but gold and silver are too soft to be used as tools.. The first really useful metal to be discovered was bronze. ...
