I couldn't confirm it, so it's almost certainly an urban legend. One of the best sites I found was: http://en.wikipedia.org/wiki/Beverage_can
One snippet from there is: When recycled without other metals being mixed in, the can/lid combination is perfect for producing new stock for the main part of the can � the loss of magnesium during melting is made up for by the high magnesium content of the lid. Also refining ores such as bauxite into aluminum requires large amounts of electricity, making recycling cheaper then smelting.
