@Bamps - cobalt nickel separation
I followed that link and had a good laugh, reminding myself why I didn't bother studying chemistry in any kind of real depth.
It appears they have tried to pound, grind, boil, drown, dissolve and bubble the ores with the metals in them over the weeks and months and come to the conclusion that they've fiddled with the samples too much that everything remains in a congealed lump, now more toxic after all the reagents they added. I laughed aloud when they described achieving a slimey sample rather than a more purified end result.
More amusing was the "we'll go and try it at a mine anyway" when they discovered oxidisation was affecting their results in the lab depending on how long the bags of sample rocks were left lying around exposed to the air before they started processing them.
As you say, a tricky issue that needs more experimental work....
