IGCSE Chemistry Revision - 24 - Extraction of Aluminium

This video goes into detail about the preparation and electrolysis for the extraction of aluminium from the initial natural resource bauxite.
In addition, I also discuss the economic and environmental issues that relate to this process and hence show the importance of recycling aluminium.
