How do you purify aluminium??
You purify aluminium by electrolysisThe process is as follows: You place pure aluminium at the cathode and impure aluminium at the anodeOxidation (loss of electrons) takes place at the anode and the anode loses massPure aluminium is deposited on the cathode where reduction takes place and it gains massAll the impurities settle at the bottom of the beaker, container, etc.
