Heavy mineral sands ore deposits - Wikipedia
Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.

Economic analysis of thorium extraction from monazite
The main source of thorium is mineral phosphate monazite, which contains about 3.1 %-11.34% of ThO 2 which has the highest percentage of thorium compared to other minerals . However, monazite also contains a high amount of rare earth elements which contribute about 54 %-60% and a small amount of uranium, ranging from 0.2% to 0.4% .
