Indian Monazite – A Potential For Future Thorium Energy

India has one of the world’s largest thorium deposits - Monazite. Thorium reserves make up to 25 % of global reserves. India has about 1.12 million tons of Thorium Oxide (ThO2). Indian Thorium reserves could possibly be converted to 358,000 GW-yr of electrical energy to meet the future energy requirement.

Monazite - Wikipedia

Monazite is a primarily 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 ...
