Thulium is principally extracted from monazite ores (~0.007% thulium) found in river sands, through ion exchange. ... Thulium dust can cause explosions and fires.

14 окт. 2024 г. · It is found in small amounts in such rare-earth minerals as laterite ionic clays, xenotime, and euxenite and in products of nuclear fission.

Thulium is mostly found in monazite. The Earth's crust also has large quantities of this element amounting to about 0.2 to 1 part per million.

The chief ores are in China, US, Brazil, India, Sri lanka and Australia. Reserves of thulium are estimated to be about 100.000 tonnes. World production is about ...
