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.

Take copper sulphate solution in a glass through. Dip a carbon rod in the solution. Use it as the cathode, i.e. connect it to the negative terminal of the battery. Take a pure copper strip, dip it in the solution and use it as anode, i.e. connect it to the positive terminal. Pass electricity through the solution by closing the circuit.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This
