Thorium Th - PubChem

Thorium is a naturally occurring, radioactive substance. In the environment, thorium exists in combination with other minerals, such as silica. Small amounts of thorium are present in all rocks, soil, water, plants, and animals.Soil contains an average of about 6 parts of thorium per million parts of soil (6 ppm). More than 99% of natural thorium exists in the form of thorium-232.

Thorium - Minerals Education Coalition

Thorium and uranium are the only naturally occurring actinides that are sufficiently common they can be mined. Thorium is obtained from the minerals monazite and thorianite (thorium dioxide). Thorium occurs as a significant impurity in the minerals zircon, titanite, gadolinite and betafite. It is mined in Australia, Canada, the USA, Russia and ...

Mineral Resource of the Month: Thorium

2021-4-17  Thorium is a naturally occurring radioactive element usually found with other minerals, such as monazite in alkalic igneous deposits and carbonatites. Thorium has a multitude of uses. It is used to generate power, produce light, transmit energy, resist ultra-high temperatures, impart strength to metals and control electrical currents.
