Often, it is an unwanted nuisance in Rare Earth refining.
"What to do with the thorium" is one reason we shut down our R.E. mines and let China hold the World hostage with their monopoly of Rare Earths like cerium and lanthanum.
So the chinese would be crazy not to exploit their thorium.
Interesting. I’ll talk to one of my buddies about it he’ll tell me all I need to know.
