One big hurdle, of course, is the efficiency/speed of bioremediation (bioengineers are working on that one, you can be sure). Another problem is how to get the bacteria in contact with the metals; water could be pumped through a filtration system (bacterial filters), but you can't pump soil. Directly applying the bacteria to the soil would require removing the bacteria and all sequestered metals after the fact- not sure how to do this effectively, either. Leaving the metals behind would defeat the purpose. The bioengineers will have to construct bacteria that work significantly faster, I think, to make soil remediation via bacterial activity feasible.

      Yes, it would have an economic impact; no, it's not necessarily appropriate to conclude that it would be a seriously negative one.

      The major currencies of the world (US dollar, Euro, Yen, GB Pound, etc.) are not backed by gold as they would have been decades or centuries ago. Without question there are still individuals, corporations, and governments that maintain some of their wealth in the form of gold bullion or other precious metals, but most don't (or shouldn't have!) put all of their eggs in one basket.

      Compare the inconvenience and hardship suffered as a result of these temporary economic dislocations with the industrial benefits of having large amounts of low-cost gold available. Gold is incredible stuff--nearly completely corrosion resistant, hypoallergenic, malleable, ductile, electrically conductive...

      To take a historical example, at the beginning of the twentieth century, the world's largest supply of nitrates came from Chilean saltpeter. There were concerns about the supply running out--Chile supplied something like 60% of the world's nitrates, but those mines were not bottomless. Chilean mining cartels also felt no qualms about gouging the Allies in World War One. Highly unfortunate this was, because the nitrates sourced there were used to produce fertilizers and explosives--both staples of twentieth century life.

      The development of the Haber process to generate ammonia directly from nitrogen and hydrogen gases changed that. Since the availability of nitrogen fertilizer was no longer limited by the availability of saltpeter deposits, modern agriculture became possible. Also, since any industrialized nation can build their own ammonia plants, the price of nitrates is no longer fixed by a mining cartel.
