Mining landfills is not as practical as not putting it in the landfill to start with, there is very little that should ever end up in a landfill! but it ends up there because we are lazy, mining land fills takes energy and resources too.
I've never seen a prediction before of when we might run out of copper, but the amount of copper we use is amazing, same with silver, silver has so many practical uses that I wish it wasn't used for jewelry, gold on the other hand has very few uses and the uses that it does have require very little of it, but it's used as a currency so it's value is absurdly high!
