BEIJING, July 4 (Xinhua) -- Chinese geologists have discovered two new minerals at the world's largest rare-earth mine in northern China, the Chinese Academy of Sciences (CAS) has announced. The two new niobium-scandium minerals, named as Oboniobite and Scandio-fluoro-eckermannite, were di...
In the paper, a team of international researchers report the rare scientific discovery they found in the mine: a “super-deep” diamond encasing the mineral calcium silicate perovskite (CaSiO3), which is the fourth-most abundant mineral in the Earth but has never been found in nature until no...
Geochemistry: Rare mineral found on EarthVolcanic rocks from Israel contain the first known occurrence on Earth of a titanium-rich mineral called tistarite. The discovery suggests that deep-Earth chemistry may differ from what scientists had suspected....
Rare earth elements became known to the world with the discovery of the black mineral ytterbite (also known as gadolinite) by Lieutenant Carl Axel Arrhenius in the year 1787, in a quarry in the village of Ytterby, Sweden. Many of the rare earth are named for the scientists who discovered...
In January 2023, LKAB announced the discovery of the largest known deposit of rare earth elements in Europe. The deposit, Per Geijer, located in Kiruna, is an iron ore deposit with high levels of both phosphorus and rare earth oxides. The grade of rare earth elements is ten times higher ...
Hou said exploring medium and heavy ion-adsorption rare earth deposits is challenging due to their relatively low overall content and lack of distinctive mineral forms easily identified in the field. Unlike deposits of iron or leadzinc ore, whic...
The complete analysis of a cerium-earth mineral to determine its ∑ is time consuming. The discovery of a direct relationship between ∑ and the Ce/(Nd + Y) atomic ratio in cerium earth minerals allows a rapid determination of ∑ from spectrograms obtained in a previously described method ...
Rare earth elements(REEs) represent the group of 17 elements comprising 15 lanthanides, plus yttrium (Y) and scandium (Sc) (Table 1). Among the REEs, yttrium was discovered first in 1794 by a Finish chemist, Johan Gadolin who isolated an oxide and called it “yttria,” in a mineral coll...
Rare earth rare earth ore inthe crust is mainly in mineral form, there are three main types: its occurrenceas basic elements of rare earth minerals, in the form of ionic compounds occursin the crystal lattice, the mineral composition of essential components. Thismineral is often referred to as...
Researchers from Trinity College Dublin have shed new light on the formation mechanisms of a rare earth-bearing mineral that is in increasingly high demand across the globe for its use in the green energy and tech industries. The discovery has important economic implications because there are ...
