copper extraction and purification - chemguide

Electrolytic refining. The purification uses an electrolyte of copper(II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the cathode, copper(II) ions are deposited as copper. At the anode, copper goes into solution as copper(II) ions.

Electrolysis - Refining Of Copper - Anode, Solution, Cathode ...

In the electrolytic refining of copper, the impure copper is made from the anode in an electrolyte bath of copper sulfate, CuSO 4, and sulfuric acid H 2 SO 4. The cathode is a sheet of very pure copper. As current is passed through the solution, positive copper ions, Cu 2+, in the solution are attracted to the negative cathode, where they take on electrons and deposit themselves as neutral copper atoms, thereby building up more and more pure copper on the cathode.

Electrorefining of Copper

Fire-refined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques.

Electrolytic refining - Oxford Reference

Copper(II) sulphate solution is the electrolyte. Copper dissolves at the anode: Cu Cu 2+ +2e, and is deposited at the cathode. The net result is transfer of pure copper from anode to cathode. Gold and silver in the impure copper form a so-called anode sludge at the bottom of the cell, which is recovered.
