In a similar vein ive often thought it would probably be cheaper to "mine" old landfill sites then dig for new metals etc.  Not so long ago we used to throw away all cans/glass etc plus electrical items which must have quite a lot of rare metals in them plus copper etc.

There was a documentary (on BBC4 IIRC) fairly recently about this.
