Adsorption Behaviors of Lanthanum (III) and Yttrium (III) Ions on Gibbsite

open access: yes, 2023
The enrichment process of rare earth elements in ion-adsorbed rare earth ores and bauxite is potentially related to the adsorption of rare earth elements by gibbsite.

The adsorption of perfluorooctanoic acid and perfluorooctane sulfonic acid by gibbsite

open access: yesVadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Perfluoroalkyl substances (PFAS) represent a global source of environmental contamination and have been linked to a wide variety of health issues. Despite their abundance, little is known about the mechanistic interactions between PFAS and common soil minerals.

Acid Leaching Performance of Gibbsite-type Bauxite with High Iron Content

open access: yesKuangchan zonghe liyong, 2022
High-iron bauxite with low A/S ratio cannot be extracted economically by Bayer process. Taking a low-grade gibbsite ore abroad as the research object, the acid leaching performance of gibbsite was studied by using hydrochloric acid as leaching medium ...

Reaction mechanisms of phosphate with Al(OH)3 and a sandy soil [PDF]

open access: yes, 1979
Al(OH) 3 is a very effective sorbent for orthophosphate especially at low pH. At low phosphate concentration c p , phosphate is adsorbed by an exchange mechanism with singly coordinated OH(H) groups residing on the surface of the Al(OH) 3 . In chapters 2

Crystallization of gibbsite from synthetic chromate leaching solution in sub-molten salt process

open access: yes, 2015
For the clean and economical production of chromium compounds, it is crucial to remove aluminates from chromate alkali solutions and utilize aluminum-containing compounds.

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

open access: yesGeophysical 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 ...

Adjustment on gibbsite and boehmite co-precipitation from supersaturated sodium aluminate solutions

open access: yes, 2010
Gibbsite is the usual precipitation product from alumina refineries with either Bayer or sintering process. However, the advantage of boehmite precipitation over gibbsite precipitation is the significant energy saving in the subsequent calcination step ...

Microwave digestion of gibbsite and bauxite in sodium hydroxide [PDF]

open access: yes, 2020
It was hypothesized that bauxite digestion may be improved by using microwave heating as it has been shown in literature that some material processes have improved efficiency.

Concomitant Mineral Carbonation and CO2 Reduction in Short‐Term Water‐Basalts Reaction: Difference Between Basaltic Glass and Basaltic Crystals

open access: yesGlobal Challenges, Volume 10, Issue 8, August 2026.
Short‐term CO2–water reactions show that crystalline basalt undergoes more extensive carbonation than basaltic glass and is associated with detectable H2 and higher CO and CH4 concentrations. This contrast is consistent with the greater early reactivity of Fe‐ and Mg‐bearing crystalline phases, indicating that basalt mineralogy influences coupled ...

Synthesis and Characterization of Boehmites Obtained from Gibbsite in Presence of Different Environments [PDF]

open access: yesMaterials Research, 2016
In this study, results related to boehmite synthesis by hydrothermal processes starting from a Bayer commercial gibbsite are reported. The processes have been conducted from aqueous suspensions with initial acidic or alkaline pH, without or with acetate ...
