Why is a lot of energy needed to extract Aluminium from ...

2020-3-7  Why is a lot of energy needed to extract Aluminium from its ore? It is expensive, largely because of the amount of electricity required in the extraction process. The ions in the aluminium oxide must be free to move so that electricity can pass through it. Aluminium oxide has a very high melting point (over 2000°C) so it would be expensive to ...

2017-3-27  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.
