You might've picked the worst example, as aluminium refining is an electrolysis process which is extremely energy intensive (Iceland imports a lot of ore and exports a lot of metal for this reason).
I might agree with you if you back your statements up with some data, but it does go against what I've always read about aluminium in particular.
