	Bastnasite
		In geology, the mineral bastnasite is one of a family of three carbonate-floride minerals.
		There is bastnasite-(Ce) with a formula of (Ce, La)CO There is bastnasite-(La) with a formula of (La, Ce)CO There is also bastnasite-(Y) with a formula of (Y, Ce)CO Most bastnasite is bastnasite-(Ce), and cerium is by far the most common of the rare earths in this class of minerals.

		Bastnasite is a mixed lanthanide fluoro-carbonate mineral (Ln F CO3) that currently provides the bulk of the world's supply of the light rare earth elements.
		Bastnasite is widely consumed as it is a major source of feed for downstream recovery of the individual rare earth elements.
		Bastnasite can also be used in television faceplates and glass melts for ultraviolet shielding and de-coloring as well as for sulphur-getting in alloying agents.

	Process for obtaining permeability logs using radioactive drilling mud additives - Patent 4691772
		The method of claim 13 wherein the gamma ray emitting nuclides are found in naturally occurring minerals selected from the group consisting of bastnasite, cerium fluoride and cerium oxide, and mixtures thereof.
		In the preferred embodiment of this invention, the radioactive particles added to the drilling mud are mud weighting particles for increased mud density, such as barite, containing gamma-ray emitting nuclides of sufficiently low concentration to avoid radiation hazards to humans and to comport with existing governmental health and safety regulations.
		For example, thorium-bearing bastnasite occurs mechanically mixed with barite as major constituents of the ore from the Mountain Pass Mine in San Bernardino County, California.

		The major commercial source of praseodymium is the rare-earth minerals monazite and bastnasite.
		Praseodymium was discovered in 1885 by C. Von Welsbach, who separated Mosander's "didymium" into two components, the earths neodymia and praseodymia.
		The first step in obtaining praseodymium is to treat monazite, bastnasite, or another ore to separate the lanthanides from each other.
