Facts About Thorium - Live Science

Thorite is the most common thorium mineral. Thorium is a highly radioactive element and could be used as a replacement for uranium in nuclear power generation. It is estimated to be three times as common as uranium and all the thorium in the Earth's crust could have more potential energy than both uranium and the fossil fuel reserves combined.

Thorite: The mineral Thorite information and pictures

Thorite is named for its content of the rare element thorium. It is isomorphous with Zircon and occurs in the same crystal habits. Thorite is the most prevalent mineral containing the radioactive element thorium. However, it is not as important as the primary thorium ore, Monazite, since the extraction process of the ore from Thorite is more difficult then that of Monazite.

Thorium Ore - an overview | ScienceDirect Topics

Thorium was discovered by J. J. Berzelius in 1828 when he isolated a new oxide from a Norwegian ore then known as thorite. He named the oxide thoria, and the metal he obtained by reduction of its tetrachloride with potassium he named thorium. (Later, in 1841, B. Peligot used the same method to prepare uranium metal for the first time.)
