Ann: Exceptional Leach Recoveries of Rare Earth Elements at Innou, page-34

because what he has posted is accurate.

Its akin to throwing a human body in lime and then saying its 100% recoverable. If you use a strong acid of course you are going to get a high recovery, it literally melts everything away.

Why is that bad? because it is not economical to process rees with strong acids. They're expensive and the acid is consumed. This is a known factor. Hence why neutral pH testing like ANSTO is the only way to determine if there is potential for economic clay hosted rare earths.

@setfire2thehive has done plenty of posts on this and publicly available podcasts explaining in depth.

You are arguing with fact because you don't like the poster that delivered the fact. Is Mongy right on everything else? I don't know and I don't care. I'm correcting the original bs posted here saying that this is an excellent result because its not.
