Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ56Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust from French Guiana, reveal the response of Fe hosted in laterite to past changes in ...

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).

A Generalized Predictive Model for Displacement Washing of Partially Reslurried Filter Cakes

Chemical Engineering &Technology, Volume 49, Issue 8, August 2026.
During displacement washing, partial reslurrying of the filter cake surface frequently occurs as an undesired side effect of wash liquid application, causing premature contamination of the wash liquid through mixing with cake impurities. This contamination can limit both washing efficiency and the achievable washing result.

Toward the bioleaching of bauxite residue by Gluconobacter oxydans

Journal of Applied Microbiology
Abstract Aim This project evaluated a biologically mediated strategy to solubilize several rare earth elements and critical raw materials, including scandium, from bauxite residue. This work seeks to expand on previous research on contact leaching with bauxite.

Home Range and Habitat Selection of the Endangered Red Goshawk (Erythrotriorchis radiatus) Across Australia's Tropical Savannas

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We used long‐term GPS tracking to quantify home‐range size and habitat selection of the endangered Red Goshawk across tropical savannas of northern Australia. Red Goshawks occupied extensive overall home ranges, with well‐defined core ranges centred on nest sites.

Vermicompost and gypsum amendments improve aggregate formation in bauxite residue [PDF]

, 2017
Improving aggregate formation and stability of bauxite residue is essential for the development of a soil on the residue. Effects of gypsum and vermicompost on related chemical and physical conditions of bauxite residue were studied in a laboratory ...

Experimental Simulation of Long Term Weathering in Alkaline Bauxite Residue Tailings

Metals, 2015
Bauxite residue is an alkaline, saline tailings material generated as a byproduct of the Bayer process used for alumina refining. Developing effective plans for the long term management of potential environmental impacts associated with storage of these ...

Characteristics and Material Flows of Diary Packaging in Municipal Solid Waste: A Case Study of Plastic Yoghurt Cups in Vienna

Global Challenges, Volume 10, Issue 8, August 2026.
Consumer dismantling behavior of yoghurt cups has been quantified in Vienna. Three‐component cups (with carton wrap) are increasingly present on the market but are rarely correctly dismantled and disposed of correctly, leading to mis‐sorting and loss of recyclable material.

Improvement of aggregate-associated organic carbon and its stability in bauxite residue by substrate amendment addition [PDF]

, 2020
Bauxite residue has extreme alkalinity, poor aggregate stability, and low organic carbon content, which limits plant growth on large expanses of bauxite residue disposal areas.

Combined Decarbonizing Technologies for Treatment of Bauxite Residues

Waste
This study explores both pyrometallurgical and hydrometallurgical methods for decarbonizing and recovering valuable metals from bauxite residue, with hydrogen plasma reduction and direct acid leaching as the primary approaches.
