Utilization of Bauxite Slag for the Purification of Industrial Wastewaters

The color removal of dye wastewater by magnesium chloride/red mud (MRM) from aqueous solution

“…7-9 show the plots of the rate of removal of three dye solutions versus the pH values for different coagulants. It is reported [26][27][28][29] previously that RM is believed as a promising material for coagulant production, due to high contents of Fe and Al in red mud and porous surface. Meanwhile, it is also found that NaOH is capable of serving as a coagulant and can give a certain degree of color removal effectiveness in the decolorization process.…”

Synthesis and characterization of ferrimagnetic glass‐ceramic frit from waste

“…The large amount of sludge generated during the process and the cumulative value of this determine the importance of valorization. Researches regarding the use of red mud include metallurgic processes or catalysis in waste treatment . But it is by far its use in the manufacture of construction elements the most extended option, as this is an industry that needs large amounts of raw materials .…”

“…Researches regarding the use of red mud include metallurgic processes or catalysis in waste treatment. 11,12 But it is by far its use in the manufacture of construction elements the most extended option, as this is an industry that needs large amounts of raw materials. 13,14 As well, significant researches are carried out on the production of glasses and glass-ceramics from bauxite residue.…”

Preparation of coagulant from red mud and semi-product of polyaluminum chloride for removal of phosphate from water

“…As a result, fi nal disposal of RM faces a huge challenge due to its high alkalinity and large amount. In previous studies, RM has been used for preparation of adsorbents [5][6][7][8][9][10][11], coagulants [12][13][14][15], catalysts [16]. However, there has been little report on the utilization of the alkali in RM for the preparation of coagulants.…”
