The structure of bastnasite is made up of stacks of carbonate ion layers and CeF layers. The CeF layers form flat hexagonal sheets with each cerium bonded to three fluorines. The carbonate layers are more complex with angled carbonate triangular groups.
Where is bastnaesite found?
Bastnaesite occurs in pegmatites near Pikes Peak, Colo. and with fluorite in Lincoln County, New Mexico; it is commercially mined at Mountain Pass, Calif. For detailed physical properties, see carbonate mineral (table).
Is Bastnaesite radioactive?
Bastnasite-(Ce) is Radioactive as defined in 49 CFR 173.403. Greater than 70 Bq / gram.
What is Bastnasite used for?
Primary Commodity Uses: Rare earth elements are used to make strong magnets for smartphone speakers, microphones, vibration motors, smartphone screens, as well as many other high-tech applications.
Is bastnaesite a mineral?
The mineral bastnäsite (or bastnaesite) is one of a family of three carbonate-fluoride minerals, which includes bastnäsite-(Ce) with a formula of (Ce, La)CO3F, bastnäsite-(La) with a formula of (La, Ce)CO3F, and bastnäsite-(Y) with a formula of (Y, Ce)CO3F.

Where can I mine neodymium?
Neodymium is primarily mined as part of a conglomerate with other rare earth elements in the monazite and bastnaesite mineral deposits. Historically, a single mine in California produced most of the world’s rare earth minerals, but since the early 90s, China has become the world’s primary source.
Is Bastnaesite a mineral?
How is cerium used?
Uses of cerium Cerium is a component of mischmetal, used in the manufacture of alloys for cigarette lighters. Cerium oxide is used in incandescent gas mantles, as a glass polishing agent and as a catalyst in self-cleaning ovens.
Which metal is extracted from Bastnasite?
Cerium
Cerium in most natural bastnäsites usually dominates the others. Bastnäsite and the phosphate mineral monazite are the two largest sources of cerium, an important industrial metal.
What is the chemical formula for bastnaesite?
The mineral bastnäsite (or bastnaesite) is one of a family of three carbonate-fluoride minerals, which includes bastnäsite-(Ce) with a formula of (Ce, La)CO 3F, bastnäsite-(La) with a formula of (La, Ce)CO 3F, and bastnäsite-(Y) with a formula of (Y, Ce)CO 3F.
How many grams are in a bastnasite La?
Bastnasite-(La) is Radioactive as defined in 49 CFR 173.403. Greater than 70 Bq / gram. Estimated Maximum U.S. Postal Shipping Size (10 mRem/hr limit, Unshielded 10 cm box) 507.73 ±126.93 grams of pure Bastnasite-(La) .
What is the difference between bastnäsite-(Ce) and bastnä Site-(Y)?
There is bastnäsite- (Ce) with a more accurate formula of (Ce, La)CO 3 F. There is also bastnäsite- (La) with a formula of (La, Ce)CO 3 F. And finally there is bastnäsite- (Y) with a formula of (Y, Ce)CO 3 F. There is little difference in the three in terms of physical properties and most bastnäsite is bastnäsite- (Ce).
Is bastnäsite a rare earth element?
Most bastnäsite is bastnäsite- (Ce), and cerium is by far the most common of the rare earths in this class of minerals. Bastnäsite and the phosphate mineral monazite are the two largest sources of cerium and other rare-earth elements .
