Stabilization of Red Mud - A Review
SSRN Electronic Journal, 2020In the present study red mud is used as a substitute of soil for construction of pavement layers. Red mud is produced in slurry form from the processing plant and disposed into red mud pond which causes environmental pollution in terms of air, land and water. In dry condition it causes air pollution, harmful to eyes and in slurry form it causes harmful

The red mud slurry “stacking” method used in many Alcan Plants has been developed in the 1980’s. The aim of this technique is to use minimum space for the disposal of the residue and to rapidly obtain consolidated material. The consistency of the mud slurry plays a key role in the steepness (angle) of the stacking slope.

Electrorheological Properties of Polyaniline/Red Mud Composite
International Journal of Polymer Analysis and Characterization, 2008Abstract In this study, electrorheological (ER) properties of polyaniline (PANI) and polyaniline/red mud (RM) composites were investigated. Polyaniline and polyaniline/red mud (PRM) composites were prepared by oxidative polymerization. PANI and PRM particle-based ER suspensions were prepared in silicone oil (SO) and their ER behavior was investigated ...

Calcification–carbonation method for red mud processing
Journal of Hazardous Materials, 2016Red mud, the Bayer process residue, is generated from alumina industry and causes environmental problem. In this paper, a novel calcification-carbonation method that utilized a large amount of the Bayer process residue is proposed. Using this method, the red mud was calcified with lime to transform the silicon phase into hydrogarnet, and the alkali in ...

Phosphate removal from wastewater using red mud
Journal of Hazardous Materials, 2008Red mud, a waste residue of alumina refinery, has been used to develop effective adsorbents to remove phosphate from aqueous solution. Acid and acid-thermal treatments were employed to treat the raw red mud. The effects of different treatment methods, pH of solution and operating temperature on adsorption have been examined in batch experiments. It was

Pyrometallurgical processing of red mud
MetallurgistВысокожелезистый красный шлам Байера, содержащий более 30% железа, считается бедной железной рудой. В связи с глобальным дефицитом железа во всем мире в последние десятилетия все большее внимание привлекает вопрос о том, как эффективно использовать железо, содержащееся в красном шламе с высоким содержанием железа.

Properties and mechanism of red mud in preparation of ultra-lightweight sludge-red mud ceramics
Journal of Central South University, 2012New ultra-lightweight sludge-red mud ceramics (ULSRMC) were prepared by red mud (RM), clay and dried sewage sludge (DSS). The properties and mechanism of RM in the preparation of ULSRMC were discussed. The chemical components, thermal properties and mineral phases of RM were determined by energy dispersive X-ray (EDX), differential scanning calorimetry/

Journal of Colloid and Interface Science, 2002
In this work, red mud (RM) was chemically modified by 0.1, 1, and 5 M H(3)PO(4) solution to prepare epoxy/RM nanocomposites. The effect of chemical treatment on a RM surface was studied in terms of pH, acid-base values, N(2)/77 K gas adsorption, equilibrium spreading pressure (pi(e)), and surface free energy.

Waste Management, 2019
A novel method to activate red mud was proposed in this study. Municipal solid waste incineration fly ash (MSWIFA) and red mud were utilized to prepare red mud-based geopolymer materials (RGM). The hydration characteristics of RGM were studied by X-ray diffraction, scanning electronic microscopy, and Fourier transform infrared spectroscopy.
