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 is an aluminium compound. with a lower melting point than aluminium oxide. The use of cryolite reduces some of the energy costs involved in extracting aluminium.
energy expenditure in extraction of aluminium. Cost And Energy Expenditure Of Extracting Aluminium Extraction of aluminium aluminum recycling sodium by electrolysis e.g. how do we extract aluminium from its bauxite ore containing aluminium oxide of energy in the extraction of a reactive metals and makes aluminium expensive to must be purified prior to electrolysis adding to the.
Jul 15, 2011· Using the figures above this means that 621 billion kilowatt hours of electrical energy were used in the production of aluminium. To put that in perspective, the total world production of electrical energy was 20261 billion kilowatt hours, meaning that more than 3% of the world's entire electrical supply went to extraction of aluminium.
