Wyoming Mining Association: Rare Earths Mining …

Rare earth elements (REE) are naturally occurring materials with unique properties that make them essential to new technologies. REEs include 17 elements that share similar chemical properties, which give them the ability to discharge and accept electrons, making them an integral component of many modern day electronic, optical, magnetic, and catalytic uses.

Bastnäsite - Wikipedia

Bastnäsite is closely related to the mineral series parisite. The two are both rare-earth fluorocarbonates, but parisite's formula of Ca(Ce, La, Nd) 2 (CO 3) 3 F 2 contains calcium (and a small amount of neodymium) and a different ratio of constituent ions.Parisite could be viewed as a formula unit of calcite (CaCO 3) added to two formula units of bastnäsite.

Froth flotation of xenotime

Froth flotation as a fundamental method for processing complex minerals is commonly applied to the surface chemistry and beneficiation of rare-earth-bearing minerals. This is due to the fact that it is possible to process a wide range of fine particle sizes and the process can be tailored to the unique mineralogy of a given deposit. Flotation effectiveness is primarily controlled by the ...

The effectiveness of surfactants, i.e., frother, depressant, and collector, can strongly influence the flotation process, including the enrichment of rare earth elements (REEs) from coal, coal by-products or fly ashes. The properties of particle size, temperature, and pH will also affect REE enrichment. Here, we report the performance of different chemicals/process parameters for the froth ...

Rare-earth element - Wikipedia

A rare-earth element (REE) or rare-earth metal (REM), as defined by the International Union of Pure and Applied Chemistry, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...
