Often a question in GCSE science exam papers is 'why is aluminium expensive?' Could someone help me out on what the answer to this question would be in an exam? It probably has to do with the extraction of the metal but I'm not sure.I know the question is vague but most exam Qs are so bear with me! Thank you!!!
Most of the expense involved in producing aluminum metal comes from needing a large quantity of electrical energy to reduce the oxidized aluminum in its ore.
