Prediction of Red Mud Bound-Soda Losses in Bayer Process Using Neural Networks [PDF]

open access: yesIranian Journal of Chemical Engineering, 2016
In the Bayer process, the reaction of silica in bauxite with caustic soda causes the loss of great amount of NaOH. In this research, the bound-soda losses in Bayer process solid residue (red mud) are predicted using intelligent techniques.

The effect of chemical and mineralogical composition of red mud on alkalinity parameters

open access: yesZaštita Materijala, 2017
Red mud is highly alkaline colloidal suspension, which remains after processing bauxite into alumina by Bayer’s proceedings. Despite repeated washing red mud keep strong alkalinity, due to the presence of residual base and a number of alkaline minerals ...

Microstructure development and fracture toughness of acid-treated carbon nanofibers/alumina composites [PDF]

open access: yes, 2012
In this study, carbon nanofibers (CNFs) having different amounts of defect were prepared by acid-treating for 0.5, 1 and 5 h and were combined with alumina. Then, the influence of the amount of defect on the CNFs on microstructure development of the CNFs/

Influence of process parameters in ion exchange on the properties of the obtained 5A zeolite powder

open access: yesZaštita Materijala
Zeolite 5A is highly regarded in adsorption processes among zeolites, making it valuable for various commercial applications. It is typically synthesized from 4A zeolite by replacing Na+ ions in the crystal lattice with Ca2+ or Mg2+ ions through an ion ...

High-pressure spark plasma sintering of MgO-doped transparent alumina [PDF]

open access: yes, 2012
Transparent alumina doped with MgO is fabricated by spark plasma sintering (SPS) under high pressures. An optimum sintering condition explored by changing the combination of the applied pressure and sintering temperature led to an in-line transmission ...

Treatment effect on the adsorption capacity of alumina for removal fluoride

open access: yesNano Biomedicine and Engineering, 2010
Acid and base treated alumina particles were studied to assess their capacities for the adsorption of fluoride from aqueous solutions. The surface morphology of untreated alumina was analyzed by SEM and its crystal structure was checked by XRD, and was ...

The effect of alumina nanofillers size and shape on mechanical behavior of PMMA matrix composite [PDF]

open access: yesJournal of the Serbian Chemical Society, 2014
Composites with the addition of alumina nanofillers show improvement in mechanical properties. The PMMA polymer was used as a matrix and two different types of nanofillers, having extremely different shapes were added in the matrix to form the ...
