Oct 16 2014nbsp018332REFINING OF ALUMINIUM HOOPS PROCESS Aluminium is refined by an electrolytic method. The electrolysis is carried out in a carbon lined iron tank which is filled with three molten layers of different specific gravity one over the other. The top layer consists of pure molten Aluminium and acts as cathode.

The refining process also rearranges the structures and bonding patterns of the basic molecules into different more desirable hydrocarbon molecules and compounds. The type of hydrocarbon paraffinic naphthenic or aromatic rather than the specific chemical compounds present is the most significant factor in the refining process.
