I think @RocketGuy and @dabbler have the best take on this so far. The difficulty with getting that stuff down to Earth where the metals (and any other materials) can be reprocessed will be getting something UP there first to carry them down, because they will have to be carried to be of much good to us. If they’re allowed to fall to Earth naturally (which they will do eventually anyway) then most of them will burn up in the atmosphere and though oxides of the metals will certainly all fall to ground (or ocean), they’ll be so widely scattered as to be useless.
So if you want to use those metals on the ground, you need to build a craft large enough to harvest and carry them down to ground again inside the craft. And that is going to be a hugely expensive undertaking and launch / recovery operation.
