I dont understand this.
You would have to be pretty unintelligent to use acid to treat a limestone ore such as agua fria, but then again the same can be said if you think you can leach spodumene without HF. Why not use Lies-Na. Oh thats right, this way, there is more news flow for the under-informed.
I guess thats what you get when a pseudo geologist masquerades as metallurgist, hey rokkett.
