Is monazite a rare-earth mineral?

Monazite is a brown crystalline mineral consisting of cerium, lanthanum, other rare earth elements, and thorium. Monazite usually occurs in small, isolated crystals or grains that are resistant to weathering and become concentrated in soils and sediments downslope from the host rock.

How is monazite sand a valuable resource?

The radioactive thorium is present in monazite sand. So it is highly valuable because thorium can be extracted from monazite sand for use as a nuclear fuel.

Which state has largest reserve of thorium?

The correct answer is Kerala. Kerala is the largest producer of Thorium in India.

Why is thorium not used?

Thorium cannot in itself power a reactor; unlike natural uranium, it does not contain enough fissile material to initiate a nuclear chain reaction. As a result it must first be bombarded with neutrons to produce the highly radioactive isotope uranium-233 – ‘so these are really U-233 reactors,’ says Karamoskos.

What stone is more valuable than a diamond?

Painite. The most valuable gem that is not a diamond is one that many have never heard of. Painite is an interesting brick-coloured gemstone. It is the most valuable non-diamond gem priced at £41,000-£49,000 ($50,000-$60,000 US) per carat.
