Energy - Cost

Extraction of Metals. 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.

how much energy is used to extract aluminium

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 molten cryolite.

U.S. Aluminum Production Energy Requirements: Historical ...

Process Challenge. Elemental aluminium cannot be produced by the electrolysis of an aqueous aluminium salt, because hydronium ions readily oxidize elemental aluminium. Although a molten aluminium salt could be used instead, aluminium oxide has a melting point of 2072 °C so electrolysing it is impractical. In the Hall–Héroult process, alumina, Al 2 O 3, is dissolved in molten synthetic ...
