Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis

Review of Development Economics, Volume 30, Issue 3, Page 1957-1972, August 2026.
ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.

Replacement of Sand with Bauxite Mining Waste in Concrete Production

Journal of Materials and Engineering Structures, 2019
The use of natural sand as fine aggregate in concrete is becoming problematic due to scarcity and pressure on mining of the resource. Alternate sources such as the use of industrial waste as replacement of natural sand in concrete are gaining popularity ...

Batteries From Reused, Recycled, and Surplus Materials

Advanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...

Determination of Available Alumina, Active Alumina and Active Silicon in Gibbsite Bauxite by Inductively Coupled Plasma-Optical Emission Spectrometry with Microwave Digestion

Yankuang ceshi, 2017
Available alumina and active silicon in gibbsite bauxite are important indicators for the quality of bauxite. These two components are commonly determined by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES).

Full Analysis of Sierra Leone Bauxite and Possibilities of Bauxite Residue Filtration

Journal of Siberian Federal University. Engineering & Technologies, 2016
Chemical analysis, classical or instrumental using ICP and the XRF spectrometry, offers complete information on elemental composition and major chemical constituents of bauxite and bauxite residues resulted from the Bayer process. The XRD diffractometric analysis provides information on quantitative mineralogical composition of these materials and it ...

A New Customizable Surfactant LLPS Strategy for Sustainable and Highly Efficient Radioactive Metal Ion Separation

Advanced Science, Volume 13, Issue 41, 22 July 2026.
A diluent‐free, customizable liquid–liquid phase separation (LLPS) platform enables highly efficient radioactive metal ion extraction and stripping. By encapsulating hydrophobic extractants into an ionic surfactant‐rich condensed phase, this LLPS system leverages synergistic electrostatic and coordination interactions.

Respirable Dust Exposure in Western Australian Mining: Trends, Variability, and Implications for Occupational Health

American Journal of Industrial Medicine, Volume 69, Issue 7, Page 540-547, July 2026.
ABSTRACT Background Mining workers are exposed to a range of respiratory hazards, including respirable dust. While exposure to respirable crystalline silica in the mining industry has been found to be common, less is known about trends in measured levels of exposure to respirable dust overall.
