Revealing cracking and breakage behaviours of gibbsite particles [PDF]

, 2020
Mitigating gibbsite particle cracking and breakage during industrial alumina production can increase the quality of smelter grade alumina product by reducing the ultrafine particle content.

Behavior of sodium oxalate in seeded precipitation process of sodium aluminate solution

工程科学学报, 2018
Sodium oxalate has negative effects on alumina produced by the Bayer process. The behavior of sodium oxalate in the seeded precipitation process of a sodium aluminate solution was investigated. The particle size and morphology of crystallization, as well

Polymer grafted gibbsite nanoplatelets via direct initiator tethering and surface-initiated atom transfer radical polymerization

, 2021
An efficient method for the preparation of polymer grafted gibbsite nanoplatelets (NPs) was proposed by direct preparation of initiator-tethered gibbsite (gibbsite-Br) NPs followed by surface-initiated atom transfer radical polymerization (SI-ATRP) to ...

Adsorption of Phosphate Ion in Water with Lithium-Intercalated Gibbsite

Makara Journal of Science, 2015
In order to enhance adsorption capacity of gibbsite (Al(OH)3 as an adsorbent for the adsorption of phosphate in water, gibbsite was modified through lithium-intercalation.

The boehmite ‘solubility gap’ [PDF]

, 2010
Boehmite, rather than gibbsite, precipitation has been proposed in the literature as a potential energy-saving modification of the Bayer process for the production of alumina. Previous experimental studies have reported that true equilibrium solubilities

Granulometric Separation of Bauxite Tailings to Metallurgical Processing [PDF]

Materials Research
The beneficiation of bauxite ore generates significant quantities of tailings, primarily composed of kaolinite and residual gibbsite, the latter still amenable to metallurgical recovery.

Low-Waste Synthesis and Properties of Highly Dispersed NiO·Al₂O₃ Mixed Oxides Based on the Products of Centrifugal Thermal Activation of Gibbsite

ChemEngineering, 2023
This study revealed an increased reactivity of centrifugally thermoactivated products of gibbsite toward aqueous solutions of nickel nitrate at room temperature as well as under hydrothermal conditions. X-ray, thermal, microscopy, adsorption and chemical

Comparison of the Raman spectra of Bayerite, Boehmite, Diaspore and Gibbsite [PDF]

, 2001
Gibbsite and bayerite are alumina trihydrate (Al(OH) 3). Gibbsite occurs abundantly in nature, usually as a major mineral component in bauxite whereas bayerite is rarely found in nature.
