Ann: Mackay Potash Project Process Engineering Update, page-7

Ppl knew leonine was present. What wasn’t known was that it wasn’t converting in certain high temp settings. It isn’t a flotation issue. It’s a conversion issue / temperature control problem from the feed. That is what the announcement is indicating. I don’t recall any potash company running as extensive feed testwork as AMN for this design (which is conventional), incl RWD. This is a results announcement from that work. If it was a decade out of touch, as you say, RWD would be up and running you’d think? Maybe Salt Lake and Kalium too with their similar issues. It’s not like WA is short of lakes…

RWD won’t give a lot of detail on its RWD process, so unclear how any of that actually works IMO.

Not sure that’s the best comparable, nor should they be compared... DYOR
