During aluminum electrolysis there must be an optimum cell voltage for a …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.This video is about extracting metals and is for Key Stage Three pupils (pupils in Years 7&8).
