Where is protactinium mined now?

Answer 1

In the past protactinium was extracted from the residues of uranium ores; now is extracted from thorium irradiated in nuclear reactors.

Protactinium is a rare element found in very small amounts in the Earth's crust. It is usually obtained as a byproduct of uranium processing, specifically in thorium ores. There are limited mining activities specifically for protactinium due to its rarity and low economic demand.
