Highlights Composite chitosan magnetic particles prepared by an original method were evaluated as a new radiocation adsorbent. The material has superior adsorption capacity both for uranyl (667 mg/g) and thorium (313 mg/g) ions. Radiocation adsorption is spontaneous and endothermic Both ions may be recovered to the extent of over 80%. This adsorbent is a good low-cost candidate for ...

Indian Monazite – A Potential For Future Thorium Energy

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 as a by-product of extracting rare earth metals. Thorium is a soft, paramagnetic, bright silvery radioactive actinide metal. Pure thorium is soft, very ductile, and can be cold-rolled, swaged, and drawn.

Thorium - CONCENTRATION OF MINERALS

Monazite is a reddish-brown phosphate mineral that contains rare-earth elements.Due to variability in composition, monazite is considered a group of minerals. The most common species of the group is monazite-(Ce), that is, the cerium-dominant member of the group. It occurs usually in small isolated crystals.It has a hardness of 5.0 to 5.5 on the Mohs scale of mineral hardness and is relatively ...
