Thorium232 is the most stable isotope of thorium and accounts for nearly all natural thorium, with the other five natural isotopes occurring only in traces. Thorium is estimated to be about three to four times more abundant than uranium in the Earth''s crust, and is chiefly refined from monazite sands [ Monazite contains % thorium ...
Only the Govt of India company IREL can deal with monazite. Here is some more information about Thorium. India has large Thorium Reserves. So can thorium be used directly in reactors? No. Thorium too would go through a three stage process which would convert it into Uranium233 and only then it can be put into reactor assembly.
In doing so, the rare earths and thorium present in the monazite are negated as a resource because it would not be economic to recover the dispersed monazite for its rare earth and thorium content. The monazite content of heavy mineral resources is seldom recorded by mining companies in published reports.
