aluminium (US: aluminum) - chemguide

The diagram shows a very simplifiedversion of an electrolysis cell. Although the carbon lining of the cell is labelled as the cathode, the effective cathode is mainly the molten aluminium that forms on the bottom of the cell. Molten aluminium is syphoned out of the cell from time to time, and new aluminium oxide added at the top.

The aluminium metal is treated with sodium hydroxide solution which removes the thin oxide layer on the surface. The clean aluminium metal is then used as the anode for the electrolysis of dilute sulfuric acid. Oxygen gas which is given off at the anode reacts with the surface of the aluminium and forms a thick oxide layer. The half equation at the anode is

Aluminium - Cost and Recycling. Aluminium is the third most abundant element in the Earth's crust after oxygen and silicon. It is the most abundant metal but it is more expensive to produce than iron because of the cost of the large amounts of electricity which are needed for electrolysis - see moles. About half of the aluminium used in the UK is recycled.

Electrolytic Cells - Chemistry LibreTexts

It is possible to construct a cell that does work on a chemical system by driving an electric current through the system. These cells are called electrolytic cells. Electrolytic cells, like galvanic cells, are composed of two half-cells--one is a reduction half-cell, the other is an oxidation half-cell.
