Investigation of REE-fluorcarbonate Minerals

, 2023
Η έρευνα αυτή επικεντρώνεται στη διερεύνηση σπανίων γαιών-φθοριανθρακικών ορυκτών, με ιδιαίτερη έμφαση στις ακτινίδες (κυρίσως Th,U). Τα δείγματα που μελετήθηκαν περιείχαν κρυστάλλους παριζίτη και μπαστναζίτη, καθώς και τυπικό πέτρωμα που εμπεριέχει σπάνιες γαίες (καρμπονατίτης).

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

Small, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Capacity of imaging spectroscopy for the characterisation of REO, REE bearing minerals and primary REE-deposits

, 2019
The spectral characteristics of Rare Earth Elements (REEs) have been poorly researched although the economic interest in these elements is increasing. This study investigates the detection of REEs using remote sensing data. For this purpose the spectral response of each individual REE has been studied with four spectrometers (HySpex (VNIR-1600 ...

OXIDES AND SILICATES OF RARE AND RARE-EARTH ELEMENTS IN ALKALINE ROCKS OF THE ILMENOGORSKY BLOCK (SOUTHERN URALS) [PDF]

Минералогия, 2017
A significant part of the REE and rare elements in the rocks of the Ilmenogorsky block forms its own minerals. Oxides and silicates of rare and rare-earth elements in alkaline rocks of Ilmenogorsky block (Southern Urals) include oxynatropyrochlore ...

Livestock grazing and geodiversity modulate wild herbivore distributions in an African community conservation area

Wildlife Biology, EarlyView.
The rapid decline of African wildlife populations demands immediate action to mitigate further losses and restore ecosystems. A key factor influencing wildlife distribution is the relationship between the energetic needs of species and the availability of forage, both in terms of quality and quantity.

Drivers of Mouse Plagues: Exceptional Rainfall Following Prolonged Drought Triggers Mouse Plagues in Southeastern Australia

Integrative Zoology, EarlyView.
This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...

On the Conceptual Overstretch of Weaponized Interdependence in Lithium and Rare‐Earth Element Markets

Global Policy, EarlyView.
ABSTRACT This paper critically examines the conceptual overstretch of weaponized interdependence (WI) in analyses of China's dominance over lithium and rare‐earth element (REE) markets. Although WI has become a central framework for interpreting EU–China economic relations, its application to raw materials often extends beyond the theory's original ...

Rare-earth and rare-metal mineralization in late granite of Syrostan massif (Southern Urals)

Литосфера, 2015
The article provides a complete list of Syrostan massif minerals, which includes 47 mineral species. It is shown that the rare-metal and rare-earth mineralization is confined to the late vein facies - granite dykes and pegmatites.

Extractability and mineralogical evaluation of rare earth elements from Waterberg Coalfield run-of-mine and discard coal

International Journal of Coal Science & Technology
This study explores the extraction of rare earth elements (REEs) from high-ash run-of-mine and discard coal sourced from the Waterberg Coalfield. Three distinct methods were employed: (1) ultrasonic-assisted caustic digestion; (2) direct acid leaching ...
