Electrolytic reactions are used purify metals and to plate metals on many types of substrates. Using the electrolytic process to purify a metal (refining): Because impurities can dramatically decrease the conductivity of copper wires, impure copper must be purified. One method of purifying copper is by electrolysis.
Copper is a good electrical conductor and is used extensively to make electrical wiring and components. However, the presence of impurity in copper can reduce its electrical conductivity. In industry, electrolysis processed is used to purify copper, and the process is called electrolytic refining .
This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using.
Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper cathode, leaving the impurities behind. Unrefined copper is about 99 % pure. It contains traces of metals such as Fe, Zn, Ag, Au, and Pt. The purity can be increased to 99.95 % by electrolytic refining in a cell similar to that shown below.
Electrolysis involves using electricity to break down electrolytes to form elements. The products of electrolysis can be predicted for a given electrolyte. Copper can be purified using electrolysis.
Purification of Copper by Electrolysis (extraction from ore above) The impure copper from a smelter is cast into a block to form the positive anode . The cathode is made of previously purified copper .

Why Copper Electrolysis? Copper is a good conductor of electricity, and is used extensively to make electrical wiring and components. The purification of copper is a form of recycling. Copper is purified further using electrolysis and we call it Copper Electrorefining (electrolytic refining). In industry this is carried out on a massive scale.
