A non renewable resource is the one which once utilized will not be available for use again because it takes millions of years for the resource to regenerate. Aluminium is a metal which is extracted from its ore like bauxite, magnetite, haematite, monazite etc. through various metallurgical processes. The formation of deposits of these ores is an extremely slow process hence once they are used up they will not be available for the generations of this era again.
