The beach sands along the coasts of India contain large reserves of strategic minerals like ilmenite, monazite, zircon, etc. Monazite mineral is primarily used as an ore for extracting rare earths particularly cerium and lanthanum. In the present study, the chemistry and distribution of monazite found in the beach sands of …
Rare-earth element - Minerals, Ores, Uses: The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as "light" or "heavy"; in the former group most of the elements present are the light-atomic-weight elements (i.e., …
Bastnasite ores contain mostly rare earths near the beginning of the series, La, Ce, Pr, and Nd. For a typical deposit the figures would be approximately 30% La, 50% Ce, 4% Pr, and 15% Nd, leaving the remaining elements at the 1% level. ... Indian Rare Earths (India) ... These properties enable it for magnetic and gravity concentration ...
This work investigated the use of a wet high intensity magnetic separation (WHIMS) in conjunction with gravity pre-concentration steps (Knelson and Falcon centrifugal concentrators) to beneficiate a rare earth ore. The results of these separation steps are related to the magnetic properties of RE minerals, based on literature and …
Ashton Mining Ltd (Ashton) and Lynas Corporation Ltd (Lynas) have established a joint venture partnership to develop and process rare earth oxides (REO's) from the Mt Weld deposit in Western Australia. The deposit is located in a deeply weathered volcanic carbonatite structure that contains approximately two million tonnes of rare earth oxides …

Mainly, monazite from beach placers is mined in India as the principal ore mineral for REE, although xenotime holds out some prospect for the future. Of India's …
1.Introduction. Rare earth elements and yttrium (REY) play a critical role in various applications, including high-tech, green-tech, and energy sectors (Hein et al., …
Rare-earth element - Abundance, Occurrence, Reserves: As noted above, the rare earths are fairly abundant, but their availability is somewhat limited, primarily because their concentration levels in many ores are quite low (less than 5 percent by weight). An economically viable source should contain more than 5 percent rare earths, …
The rare-earth elements (REEs) are strategic metals which are indispensable to the development of modern defence systems, electronic applications, and green technologies. The growing economic and strategic importance of these sectors, coupled with uncertainty in the global supply, has led to the development of many new deposits …
A final interesting application of gravity separation to rare earth mineral concentration is the use of roasting ... with a dual focus on the behavior of individual rare earth minerals as well as overall rare earth oxide concentration from ores. The most important of these techniques will likely prove to be flotation as additional reagents and ...

The Balzhe rare earth mine, renowned for its rich reservoirs of niobium, zirconium, and rare earth elements, poses a unique challenge due to its diverse and interbedded mineral composition. Despite the abundance of these elements, their valuable grade remains notably low, falling short of economic thresholds. To this end, pre …
Rare earth (RE) is an important strategic resource; however, there has been a growing concern about the environmental problems caused by RE mining, such as ammonia nitrogen pollution and heavy metal pollution. There is a limited research about the behavior of leaching agents and the fractionation of RE and heavy metal during the …
A combined "gravity-magnetic-flotation" process was developed (Li et al., 2002, Xiong and Chen, 2009), leading to significant increases in rare earth oxide (REO) content and recovery from the Maoniuping rare earth concentrate.
