Electrolysis is primarily used in mining where an electric current is passed through a solution containing dissolved metals, causing the metals to be deposited onto the hode. The electric current causes a forced oxidation-reduction reaction.
Electrolysis or electrolytic refining is a technique used for extraction as well as purifi ion of metals obtained by any refining method. In the electro- refining process, a block of impure metal is made the anode and a thin sheet of metal is made the hode.

Aluminum is extracted from aluminum oxide by a process called electrolysis. First of all, aluminum oxide needs to be in molten form to extract the aluminum ions. Aluminum oxide, however, has a high melting point. Therefore, aluminum oxide is dissolved in
Electrolysis and extraction of aluminium Electrolysis involves using electricity to break down electrolytes to form elements. The products of electrolysis can be predicted for a given electrolyte.
There are three steps to extraction: Mining, Extraction, and Purifi ion. Copper ore is first mined, or dug, from the ground. Then, the ore is contacted with a weak acid solution to dissolve the copper mineral and extract it from the rock. Finally, this solution containing copper is purified by electrolysis.
Thereafter, aluminum chloride is electrolyzed to aluminum followed by casting of aluminum ingots. The process offers faster and more efficient conversion of kaolin into aluminum chloride and subsequently to pure aluminum in presence of low temperature, thereby reducing the loss of energy efficiently.
