Rare earth elements: A review of applications, occurrence

2019-7-1  Introduction Rare-earth elements (hereinafter referred to as REE) are a group of seventeen chemical elements in the periodic table, in particular the fifteen lanthanides as well as yttrium and scandium as defined by the International Union of Pure and Applied Chemistry (IUPAC). Scandium and yttrium are considered REE since they tend to occur in the same ore deposits as the lanthanides and

The story of rare earth elements (REEs): Occurrences

2020-7-1  Rare earth elements (REEs) including fifteen lanthanides, yttrium and scandium are found in more than 250 minerals, worldwide. REEs are used in various high-tech applications across various industries, such as electrical and electronics, automotive, renewable energy, medical and defence.

Rare Earth Elements (REE) is the collective name for a group of metallic elements that always occur together in nature. They occur relatively commonly in Earth’s crust but are scarce since they are difficult to separate from each other. Production of REEs entails mining of large volumes of ore but results in low amounts of the finished product.

Rare earth elements (REE) in biology and medicine

2020-7-16  Over the last decade, rare earth elements (REEs) have been reported as essential elements for life. Although we are still far from achieving a detailed picture of the complex interactions/interferences brought by REE in living systems there is a growing attention on the potential role they may have as antagonists of important elements such as Calcium and Zinc and as catalytic centers of

An important type of heavy-enriched REE mineralisation, first recognised in southern China, has been described as an Ionic Adsorption Deposit (“IAD”) and typically is hosted by secondary clays. REE in these deposits are relatively easy

Rare Earth Elements (REE) are a collection of 30 chemical elements within the periodic table and commonly subdivided into the series of lanthanides and actinides. The term "Rare Earth" arises from the minerals from which they were first isolated (end of 18th century), which were uncommon oxide-type minerals (earths) found in Gadolinite

Rare Earth Elements (REE): Why are they strategically

2018-12-10  Rare earth elements (REE) are a group of seventeen chemical elements that occur together in the periodic table, 15 lanthanides ( Z=57 through 71), Scandium and Yttrium. All are metals and have many similar properties which often cause them to be found together in geologic deposits. That is why they are also known as rare earth metals.

Evaluating Rare Earth Element Deposits

2019-9-12  The term rare earth element is commonly abbreviated to "REE" and their oxides to "REO". To avoid confusion, it is wise in reporting REE resources to define whether yttrium is included and to report REO values rather than REE. In this paper, REO includes yttrium oxide and TREO refers to the total sum of the REO.
