Monazite Sand - an overview ScienceDirect Topics
Currently, there is little demand (and industrial need) for thorium; it is obtained mostly as a by-product from the production of rare earth metals or from the production of titanium-, zirconium-, or tin-bearing minerals from monazite deposits. 16 Little systematic exploration has therefore been conducted specifically for thorium, which explains the relative uncertainty about the total world ...

Presence of uranium and thorium in zircon assemblages
2024.4.8 Thereafter, uranium and thorium concentrations in zircon were measured by NAA and revealed that zircon contained 94-141 ppm uranium and 127-506 ppm thorium. Therefore, this noticeable amount of uranium and thorium in zircon should be taken in consideration during any mining attempt of the placer minerals present in Cox's Bazar beaches.
