Bioleaching of Phosphate Minerals Using Aspergillus niger: Recovery of Copper and Rare Earth Elements

Metals, 2020
Rare earth elements (REE) are essential in high-technology and environmental applications, where their importance and demand have grown enormously over the past decades. Many lanthanide and actinide minerals in nature are phosphates.

Mapping of potential rare earth deposits in the Schiel alkaline complex using sentinel-2B multispectral sensor

Egyptian Journal of Remote Sensing and Space Sciences, 2021
In this study, the images of Sentinel-2B multispectral sensor are used to map minerals associated with rare earth elements (REE) in an attempt to discover new potential targets for REE deposits in the Schiel Alkaline Complex of South Africa.

Genesis of silica-rich carbonatite in the Miaoya complex, Hubei Province and its implications for REE mineralization

地质科技通报, 2023
The Miaoya complex in Hubei Province hosts one of the most important REE deposit in China. This complex is composed of syenite, carbonatite (SiO2 < 10%), and a suite of silica-rich carbonatite (SiO2>30%).

Origin of heavy rare earth mineralization in South China

Nature Communications, 2017
Heavy rare earth elements (HREE) are an important global resource for many industries. Here, Xuet al. have discovered new REE minerals, which represent oxidized REE-rich fluids that metasomatized granites resulting in an enrichment of HREE, therefore ...

The signature of river- and wind-borne materials exported from Patagonia to the southern latitudes: a view from REEs and implications for paleoclimatic interpretations [PDF]

, 2004
Riverine and wind-borne materials transferred from Patagonia to the SW Atlantic exhibit a homogeneous rare earth element (REE) signature. They match well with the REE composition of Recent tephra from the Hudson volcano,and hence this implies a ...
