Where does cerium come from?

Answer 1

Curium was discovered by Glenn T. Seaborg, Ralph A. James and Albert Ghiorso in 1944 at Berkeley.

Answer 2

Cerium is primarily extracted from mineral deposits such as bastnäsite, monazite, and xenotime. These minerals are sources of rare earth elements including cerium, and are typically mined in countries like China, Australia, and the United States. Cerium is then separated from other rare earth elements through a series of extraction and purification processes.

Answer 3

The name of curium is derived from the name of Marie and Pierre Curie.

Answer 4

Only in very special chemical/physical laboratories specialized in radio/nuclear chemistry.

Answer 5

- in laboratory:

239Pu + 4He → 242Cm + 1n

- curium isotopes are also obtained in nuclear power reactors

Answer 6

Mines.
