Rare Earths / Rare Earth Elements / REE. Rare earths, each member of the group of chemical elements consisting of three elements of the group 3 (scandium [Sc], yttrium [Y] and lanthanum [La]) and the first extended series of elements below the main body of the periodic table (Cer [Ce ] by Lutetium [Lu]). The elements cerium by lutetium are ...
The Per Gejer rare earth deposit in Kiruna, Sweden, discovered in 2023, is also located in a mine where iron ore is primarily mined, and rare earths could be extracted as a by-product in the future. Alongside carbonatite intrusions, ion adsorption rocks are the second most important source of rare earths, accounting for 16% of global rare earth oxide production, particularly for heavy rare earths.
U.S. Geological Survey news release "Going Critical" The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium. Rare earth elements are an essential part of many high-tech devices. The U.S.

Die Rare-Earth-Hypothese taucht dabei als eine der wenigen übrigen Lösungen am Ende des Buchs auf. Simon Conway Morris, ein Paläontologe, argumentiert hauptsächlich, dass die Evolution konvergent verlaufen sei. Er widmet Kapitel 5 der Rare-Earth-Hypothese und zitiert sie dort zustimmend.
希土類元素（きどるいげんそ、英: rare-earth elements・REE ）またはレアアースは、31鉱種あるレアメタルの中の1鉱種で 、スカンジウム 21 Sc、イットリウム 39 Yの2元素と、ランタン 57 La からルテチウム 71 Lu までの15元素（ランタノイド）の計17元素の総称である（元素記号の左下は原子番号）。
Lytt til samtalen mellom Mette Vågnes Eriksen, general sekretær i Polyteknisk Forening og Alf Reistad, CEO i Rare Earths Norway, om forekomsten på Fensfeltet og dens betydning for det grønne skiftet og forsyningssikkerhet. Utvikling av innovativ teknologi i mineral næringen og avveininger mellom lokal natur og globalt klima.
