Aluminum Scrap - an overview | ScienceDirect Topics
For example, the production of new aluminium in the United States consumes about 3% of the national energy requirements. The amount of nonrenewable resources (e.g. coal, liquefied gas) needed to generate the electricity for the melting and refinement of scrap aluminium is much less than the production of new aluminium.

The Hall-Héroult process for the electrolytic reduction of alumina was patented at 1886 and is still currently the only industrial process for the production of aluminium. It is based upon the
smelting process of bauxite
The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium''s chief ore, through the Bayer process) in molten cryolite, and electrolysing the molten salt bath, typically in a purpose-built cell.
