Piggery effluent may contribute to the eutrophication of waterways, if it is not treated before disposal, because of high levels of phosphorus. Limes and red muds (a residue from bauxite refining) were used to remove phosphorus from piggery effluent (41 mg litre(-1) total P). Lime-based amendments were more effective than the red muds at removing phosphorus when compared at the same liquid: sol...

UNLABELLED The terrestrial isopod (Porcellio scaber) was used to assess the remediation efficiency of limestone and a mixture of gravel sludge and red mud as stabilizing agents of Pb, Zn and Cd in industrially polluted soil, which contains 800, 540 and 7mgkg(-1) of Pb, Zn and Cd, respectively. The aim of our study was to compare and evaluate the results of the biological and non-biological asse...

Abstract Utilizing industrial waste materials such as red mud alternatives to high emissions of CO 2 Portland cement will help produce integrated sustainable construction materials. Statistical analysis has been performed on the major oxides understand relationship between chemical composition and properties (e.g., workability, setting time, compressive strength, etc.) mud-based geopolymer comp...

Juvenile red snapper settle across several complex habitats, which function as nurseries for young fish. Little is known about their life history or feeding biomechanics during this time. However, recent studies have shown higher growth rates for juveniles located on mud habitats adjacent to low profile reefs, perhaps because of varied prey availability and abundance. To further investigate the...

Bauxite residue is an important by-product of the alumina industry, and current management practices do not allow their full valorisation, especially with regard to the recovery of critical metals. This work aims to test the efficiency of ion exchange resins for vanadium (V) removal and recovery from bauxite residue leachates at alkaline pH (11.5 and 13). As an environmental pollutant, removal ...

Mud Recycle is a process option for cane diffuser factories; it eliminates the need for a filter station by using the bed of shredded cane in the diffuser to separate out mud solids from the juice. This paper describes the Mud Recycle system at Maidstone mill and presents the results of a Mud Recycle trial that was carried out during the 1998 season. Maidstone switched to Mud Recycle on a perma...

The current work focuses on the manufacturing of aluminium AA 6061 composites and its tribological characterization. This is achieved by reinforcing matrix with red mud. However, uniform dispersion mud requires ultrasonic assisted stir casting use optimum wt.% TiO 2 inoculants. In this regard, composition fixed at wt.%, since addition beyond results in agglomeration, while inoculants varied fro...

In this paper, the Guangxi’s red mud disposal field is taken as the study area. Appropriate calculating parameters and boundary conditions were selected based on the survey data to build a Mohr-Coul0mb and fluid model under the plane-strain condition. FLAC software was adopted to simulate the distribution of pore water pressure, filtrate seepage paths, and leakage of the dam body under conditio...

Abstract To improve the resource utilization of solid waste, excavation abandoned soil and red mud, a by-product alumina industry, were introduced into preparation controlled low strength material (CLSM). By carrying out flowability test, bleeding test compressive relationship between properties CLSM mixture amount mud was analysed. The experiment results indicate that rate decrease with increa...
