True but look at the document.
What ggb fails to understand is.
Just because a document mentions using refractory techniques as equally as it could for any resource. It doesnt actually mean youd have to use that technique in the process chosen in the end.
These documents are ancient. Some dated 1977 and the main before 1990. Techniques have advanced a hell of a long way in 30-40 years and referring to these references as relevant today is almost a joke for many versed with more modern techniques.
This mistake of assuming Kvanefjeld could only be refractory was made by previous interested parties. Who now have to live live with the painful fact they just didnt know any better to be able to find a way to treat steenstrupine via alternative nonrefractory means..
