GCSE CHEMISTRY - Extraction of Aluminium - Energy -

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.
