Is Thorium a Non Starter in Rare Earth Minerals Recovery?

The current state of Rare Earth production is slim to non in most of the free world!  China seems to have cornered the market

of this very valuble group of minerals. One existing potential source of these minerals is in Sullivan, MO.  There are several obsticals

to their recovery. One being radio active Thorium! I am looking for ways to separate the various minerals, the safe separation of

radio active components from the other Rare Earths being of prime importance!
