Rare earths occur in nature as rare earth oxides (REO; e.g., Eu 2 O 3, Tb 4 O 7, Y 2 O 3) within minerals (e.g., bastnaesite and monazite) and are transformed into metals and compounds using metallurgical processes. The mass conversion from REO to REE metal is a stoichiometric conversion based on the REO atomic formula (on average, …
Rare Earth Elements in Australian Heavy Mineral Sands Deposits. Rare earths-bearing minerals monazite and xenotime occur in many of Australia's heavy mineral sand deposits and, up until the mid-1990s, monazite was produced from them and exported, mainly to Europe. A brief overview of these activities is given by Hoatson et.al (2011) 138.

Beyond rare earths. Nature Materials 23, 303 ( 2024) Cite this article. There is a good reason why the rare-earth elements are so called. When Carl Axel Arrhenius discovered the mineral ytterbite ...
1. Introduction. Rare earth elements (REEs) have been widely used in various fields of the modern industrial system due to their excellent optical, electrical and magnetic properties. 1, 2 Therefore, REEs are also called "industrial vitamins" and "the mother of new materials". 3 China is a major producer of rare earths, and more than 70%–80% of the …
Rare earth ore gravity separation process is based on the difference in density between rare earth minerals and gangue minerals. It is mainly aimed at the separation of rare earth minerals and gangue minerals such as quartz and calcite with low density. For example, the beach sand ore mostly uses the gravity separation method, or the ...

The rare earths, or rare earth elements (REE), are a relatively abundant group of elements consisting of scandium, yttrium, and the 15 elements of the lanthanide series of the periodic table. Scandium (Sc) is the lightest rare earth element. Scandium is present in crustal rocks in amounts greater than lead and precious metals, but it rarely ...
