Coal mines discharge low-pH acid mine drainage (AMD), which contains a variety of heavy
metals and sulfates that are extremely polluting and corrosive, posing a continuous threat to …

Currently, there is an increasing industrial demand for rare earth elements (REE) as these
elements are now integral to the manufacture of many carbon-neutral technologies. The …

Abstract Rare Earth Elements (REEs) are increasingly consumed and released into the
environment, leading to REE anomalies in aquatic systems. However, REE extraction is …

Electronic waste (e-waste) contains valuable rare earth elements (REEs) essential for
various high-tech applications, making their recovery crucial for sustainable resource …

Recycling rare earth elements (REEs) from secondary sources such as mine wastewater
has emerged as a sustainable economic strategy. In this study, microbial synthesized iron …

To enrich and recover low-concentration (10 1–10 2 ppm) rare earth elements from ores and
industrial wastes, high phase-ratio solvent extraction is favored. However, high phase-ratio …

The vulnerability of the rare earth element (REE) supply in a global context of increasing
demands entails important economic and political issues, and has encouraged several …

Coal and grain complex areas influence the geochemical characterization of REEs through
coal mining activities and agricultural production. However, there is a lack of relevant …

Rare earth elements (REEs) have been used as tracers to reveal the hydrochemical sources
and processes in groundwater systems that are usually modified by anthropogenic inputs …

With increasing demands for rare earth elements (REEs) in high-tech and futuristic
