Aluminium Extraction | ChemKey

Recycling aluminium uses only about 5% of the energy used to extract it from bauxite. Avoiding the environmental problems in the extraction of aluminium from the bauxite. Not having to find space to dump the unwanted aluminium if it wasn't recycled.

SOLVED: It takes energy to recycle waste aluminum (e.g

It takes $15 mat{kWh}$ (kilowatt-hours) of electrical energy to produce $1.0 mat{kg}$ of aluminum metal from aluminum oxide by the Hall-Heroult process. Compare this to the amount of energy necessary to melt $1.0 mat{kg}$ of aluminum metal. Why is it economically feasible to recycle aluminum cans?

Extracting aluminium

Aluminium Extraction. Aluminium is a reactive metal, above carbon in the reactivity series Its main ore, is bauxite, which contains aluminium oxide.
