    75% of all aluminum ever mined is still in circulation- its also more efficient- recycling aluminum takes 5% of the energy it takes to produce it.

        I have melted and cast ingots from thousands of dirty aluminum cans. Rinsing first is ideal of course, but all the crap floats to the top of the molten metal as slag and you can scoop it off to discard.

          I’m sure you can, but at the recycling facility it will be rejected. Look it up.
