I was going to mention that much earlier...aluminum/aluminium wasn't easily separable from bauxite until electricity could be generated at industrial scale. It also forms a protective oxidized patina very quickly so needs very little in the way of post processing to "clean it up" for re-use.
Aluminum is incredibly abundant in the earth's crust, but from what I understand it is the poster-boy for recycling because of the extreme difference in power costs between melting it down, and making it in the first place.
