Phosphate removal from wastewater using red mud

Journal of Hazardous Materials, 2008
Red 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

Stabilization of Red Mud - A Review

SSRN Electronic Journal, 2020
In 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

Experimental Investigation of Heat Conduction in Red Mud/Epoxy and Red Mud/Polyester Composites

International Journal of Thermophysics, 2014
Aluminum is one of the most abundant elements, and its global production generates an immense amount of industrial waste, which is the red mud. Thus, it is necessary to develop technologies aimed to reusing red mud. In this context, this work aims to experimentally examine variations in the effective thermal conductivity of polymers, modified with the ...

Properties and mechanism of red mud in preparation of ultra-lightweight sludge-red mud ceramics

Journal of Central South University, 2012
New 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/

Monitoring the processing of red mud

Steel in Translation, 2013
An approach is developed for quantitative chemical analysis of red mud and its processing products (hot metal and slag). Numerous macrocomponents and impurities may be determined simultaneously, over a wide content range (n × 10−n × 10−4%), by inductively coupled plasma atomic-emission spectrometry (ICP-AES), IR-absorption analysis, and gravimetric ...
