Petrography and geochemistry of pegmatite and leucogranite of Ntega-Marangara area, Burundi, in relation to rare metal mineralisation

Open Geosciences
The Ntega-Marangara area, part of the Kanyaru supergroup, Western Domain of Karagwe Ankole Belt, hosts numerous pegmatite veins related to the leucogranite. This investigation aims to characterise the granitoids, their alteration products, and rare metal

Hardness Toxicity and Multi‐Route, Multi‐Demographic Health Risks of Nitrate‐Contaminated Groundwater: A Call for Sustainable Environmental and Public Health Protection

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Groundwater contamination by nitrate and hardness poses critical challenges to environmental sustainability and public health across many regions. This research pioneers an integrated assessment of nitrate multi‐route exposure for six‐age groups and hardness toxicity in Ghana.

Pegmatites of the Mokromoskovsk granite pluton

Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія
Introduction. The Mokromoskovsky pluton is composed of light gray granites and dark gray granodiorites. Light gray granites are composed of oligoclase (35-40%), microcline (20-25%), quartz (30-35%), and biotite (2-5%).

Electrochemical Lithium‐Ion Recovery from Battery Recycling Process Water

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
A high‐purity Lithium‐ion solution was recovered by implementing a simple two‐step process combining the wet‐shredding of spent Lithium‐ion batteries with efficient electrochemical desalination. This work provides a simple and novel approach for the electrochemical extraction of Lithium ions from spent batteries.

The Goulding–Keene nepheline pegmatite near Bancroft, Ontario [PDF]

, 1976
The Goulding–Keene pegmatite consists essentially of albite, nepheline, and biotite with minor amounts of microline and other minerals. It is enclosed by plagioclase–nepheline–biotite–hastingsite–calcite gneisses and is apparently intrusive into these ...

Newly Discovered Triassic Lithium Deposits in the Dahongliutan Area, NorthWest China: A Case Study for the Detection of Lithium-Bearing Pegmatite Deposits in Rugged Terrains Using Remote-Sensing Data and Images

Frontiers in Earth Science, 2020
Rare metals, such as lithium and cobalt used in rechargeable batteries, have increased in value as demands for them escalates. Concentrations of lithium-bearing minerals are found in closed-basin brines, granitic pegmatites, and associated granitic rocks

Determination of trace element profiles in coarse-grained minerals by external millibeam PIXE - A schorl tourmaline study [PDF]

Bulletin of the Geological Society of Finland, 1995
The thick-target PIXE technique was applied to direct analysis of trace elements in tourmaline minerals. Analyses of these minerals with conventional wet-chemical methods are difficult and time consuming.

Circular Potential of Lithium‐Ion Battery Recycling Slags: Quantifying Microstructure and Elemental Distribution for a Holistic Valorization

Advanced Science, Volume 13, Issue 22, 17 April 2026.
A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.
