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.

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.

Soil Chemistry and Clay Mineralogy of an Alluvial Chronosequence from the North Carolina Sandhills of the Upper Coastal Plain, USA

Soil Systems, 2021
Temporal changes in soil development were assessed on fluvial terraces of the Little River in the upper Coastal Plain of North Carolina. We examined five profiles from each of six surfaces spanning about 100,000 years.

Coating of Gibbsite Platelets with Silica [PDF]

Chemistry of Materials, 2004
In this work, gibbsite particles are synthesized from aluminum alkoxides in an acidic environment at 85 °C. After centrifugation, coating with silica is investigated following two different methods. Practical aspects and the feasibility to produce significant amounts of material are studied. The first method, analogous to a procedure used for boehmite,

First discovery of gibbsite in Biryuzakan turquoise deposit, Northern Tajikistan

Известия высших учебных заведений: Геология и разведка
Background. In the quartz veins of the Biryuzakan turquoise deposit, a hydrothermal mineralization of varicolored gibbsite was discovered for the first time. The gibbsite varies from light- to dark blue in color, resembling turquoise. Aim.
