The methods and apparatuses described herein generate rare earth metals from ores ...
Rare earth hydroxides are recovered from the rare earth ores, e.g., monazite, xenotime andor bastnasite, by treating the ore with an aqueous solution of an alkali metal hydroxide, under agitation and essentially constant pressure, at a temperature of from about 100 to 220 C., and wherein the ratio by weight of alkali metal hydroxideore ranges from about 1.4 to 0.5, e.g., a weight ratio ...

The process of erosion concentrates denser minerals, most notably gold, into deposits known as placers. Depending on the source of the erosion products, certain rare earth elements-bearing minerals, such as monazite and xenotime, can be concentrated along with other heavy minerals.
Jul 27, 2015 On average, ore in the mine contains 6 rare earths, according to Paul Parasugo, Molycorps manager of process development. By using GPS
Pegmatites are more expensive to process than brine, but typically have higher ore concentrations 0.60. Lithium is also extracted from sedimentary rocks, including clays, which can have up to 0.7 concentrations, but this is a much less common form of deposit than brines or pegmatites Gruber, 2011.

Jun 25, 2019 Owing to its rarity and the complex and expensive process required to isolate the metal, there are very few naturally occurring ore bodies that provide economical sources of rhodium. Like most PGMs, rhodium production is focused around the Bushveld complex in South Africa.
Through a process of crushing, milling, conditioning and flotation, the rare earth elements in the ore are separated from the other elements, forming a rare earth concentrate. The concentrate undergoes a complex chemical process to purify, recover, separate and precipitate the individual rare earth elements.

Processing ores. All rare-earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic andor electrostatic separation and flotation.
