RE:WHY NOT... The minerals would still need to be removed with flotation, which does not work perfectly so some minor to trace metals would remain behind in the tailings storage. It's the tailngs storage that seems to be the main obstacle of concern, rather than transporting the concentrates. It's proven many times over that the tailings storage would have no chance of being a problem, but the ex president and son are science illiterate and became confused after a fisting trip from a luxury lodge, but excuse me for going off track.
