Enhancing solidification in one-part geopolymer systems through alkali-thermal activation of bauxite residue and silica fume integration

Case Studies in Construction Materials
This work describes the synthesis of geopolymers, a family of amorphous alumino-silicates, employing Silica fume and bauxite waste as precursor materials in an alkali-activated polycondensation reaction and the investigation of their properties.

Sintering Behavior of Red Mud Compact [PDF]

, 2008
It is beyond doubt that activity of primary industries often yields substantial amounts of byproducts. The disposal in the original industrial site is favoured by economic reasons though traditional storage in nearby dumps can be impractical owing to the

A framework for capturing indirect impacts in site‐level screening for biodiversity risks

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1376-1386, May 2026.
Abstract Site‐based industrial operations such as mining, oil and gas extraction and renewable energy development are associated with many direct and indirect impacts on biodiversity. Consideration of the full range of these impacts when selecting a buffer distance to approximate the Area of Influence (AoI) of a project is critical for effective ...

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 ...

Applying Occupancy Modelling to Inform Conservation Strategies for a Threatened Parrot Population

Austral Ecology, Volume 51, Issue 5, May 2026.
ABSTRACT Parrots provide essential ecological functions that are critical to ecosystem health, yet they are among the most threatened avian orders. Southern palm cockatoos (Probosciger aterrimus macgillivrayi) are predicted to face severe population declines due to land clearing, altered fire regimes, and low reproductive success.

Rare earth elements in karst-bauxites: a novel untapped European resource? [PDF]

, 2014
Karst-bauxite deposits form as a result of the accumulation of residual clay minerals in depressions on a karst limestone surface, and their subsequent lateritic weathering.

Use of bauxite residue (red mud) as a low cost sorbent for sulfide removal in polluted water remediation [PDF]

, 2016
Sulfide is an important pollutant in aqueous systems. Sulfide removal from polluted waters is required prior to discharge. Red mud RM) is a solid waste of bauxite processing that is rich in reactive iron oxides and consequently has the potential to be ...

Cenozoic Time Constraints on the Evolution of a Gleysol‐Ferralsol‐Podzol Toposequence, Northwest Amazon Basin, Brazil

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT Deciphering the time milestones of clay formation is crucial for modeling the evolution of major geological systems near the Earth's surface. In the present study, kaolinite samples collected along four vertical profiles within a Gleysol‐Ferralsol‐Podzol soil toposequence near São Gabriel da Cachoeira, NW Amazon Basin (Brazil) are dated using ...
