There are more than 200 minerals that contain REE. 7,8 The most common rare-earth minerals are monazite and bastnäsite (Figure 1a–b and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REE-bearing monazite is a complex phosphate. 5 Bastnäsite, …
A review of the beneficiation of rare earth element bearing minerals
The term rare earth elements (REEs) refers to the fifteen metallic elements of the lanthanide series, coupled with the chemically similar ytrrium, and occasionally scandium (Gupta and Krishnamurthy, 1992). These elements are typically split into two sub-groups, the cerium sub-group of "Light" rare earth elements (LREEs) which includes La …
What is a rare plant?
What is a Rare Plant? Rare plants may be scarce because the total population of the species may have just a few individuals, or be restricted to a narrow geographic range, or both. Some rare plants occur sparsely over a broad area. Other rare plants have many individuals, but these are crowded into a tiny area; in some cases, a single county or ...
Pyrometallurgy and electrometallurgy of rare earths
The minimum rare earth oxide (REO) grades of traditional rare earth minerals (bastnaesite, monazite, Xenotime) and non-traditional minerals such as ion-adsorbed for industrial mining are about 1.5% – 2.0% and 0.06% – 0.15%, respectively. This suggests, rare earth mineral deposit with concentrations less than these cannot be …
