Microbes That Clean Up Contaminated Mine Sites

Primary thought: I think this is really great news. Mine tailings are really nasty, so hopefully this type of thing could also work on other legacy industrial projects or future contamination.

Secondary thought: This is a long shot, but if anybody here studies this type of thing, could this ever be used to isolate and concentrate the contaminants in the tailings? For example, could we pull out and concentrate all the mercury, REE, and so on and recycle them?
