In this study, the MgCl2/red mud system (MRM) was used to investigate the color removal efficiency of dye solutions. Parameters such as the effect of the dosage of red mud (RM) and MgCl2 have been studied. The effect of pH on the conversion rate of Mg2+ has also been studied. The color removal efficiency of MRM was compared with that of PAC/RM and PAC/NaOH. Meanwhile, the color removal efficien...

Contamination of water resources with petroleum products is a serious environmental problem. The current study was carried out to investigate the effect of using raw and heat activated red mud (RM) as adsorbent to remove insoluble fraction of gasoline from aqueous solution. Some parameters such as pH, contact time, adsorbent dose and initial concentration were optimized in adsorption process to...

To maximize the utilization of red mud in geopolymers, a mud–metakaolin (RM-MK) geopolymer and mud–fly ash (RM-FA) were prepared, respectively. The effects content on compressive strength microstructure geopolymers investigated under three different curing conditions. results showed that decreased linearly with an increase content, whether at room temperature or 80 °C. Surprisingly, autoclave, ...

red mud (rm), a waste tailing from alumina production, (as an important environmental problem), can be used as a strong absorbent pollutant. in this study, the modified red mud (mrm) and pillared clay (pilc) were used for the removal of arsenate from water. the modified red mud (mrm) and pilc complex were characterized using xrd, sem and xrf microanalysis. the adsorption of arsenate on modified...

Performances of two common types of red mud, Bayer red mud and Sintering red mud, were investigated in this research. Their compositions, mechanical properties and microstructure characterization were measured through XRD, TG and SEM analysis. Their shear strength, particle size, density and hydraulic characteristics also had been performed. Huge differences between the basic mineral types of t...

Jajarm Alumina Plant, the only Alumina powder producer in Iran, generates 500,000 tons of red mud annually. The commonest method for final disposal of red mud in Iran is Tailing dam which is neither cost-effective nor environmentally-friendly. The main objective of this study is to evaluate the possibility of red mud recovery to be used for stabilization of loose soils. Red mud samples have bee...

With increasing production of red mud, the environmental problems caused by it are increasingly serious, and thus the integrated treatment of red mud is imminent. This article provides an overview of the composition and the basic characteristics of red mud. The research progress of safe stockpiling and comprehensive utilization of red mud is summarized. The safe stockpiling of red mud can be di...
