Bauxite residue is a kind of strong alkaline waste produced in the production of alumina. Its
long-term storage poses a potential threat to the environment. With the tightening of …

Contaminants such as nitrogen (N), phosphorus (P), dissolved organic carbon (DOC),
arsenic (As), heavy metals, and infectious pathogens are often associated with agricultural …

Bauxite residue has been continuously produced since the inception of the
alumina/aluminium industry in the late nineteenth century. The global inventory of bauxite …

In this paper activated seawater-neutralized red mud, herein referred to as activated Bauxsol
(AB), is used as a novel adsorbent for removing inorganic arsenic (As) from water. The …

A lama vermelha, resíduo da indústria de beneficiamento do alumino, é gerada a partir do
refino da bauxita para produção de alumina (Al2O3) através do processo Bayer. Este …

Red mud remains the largest environmental issue for the alumina industry due to its high pH
(> 13), fine-grained nature (> 90% is< 10μm), elevated sodium concentration (> 50g/kg), and …

The growing concern over environmental contamination by pharmaceutical compounds has
drawn the attention of the scientific community and regulatory bodies worldwide. It is …

Bauxite residues from the alumina industry are highly alkaline and should be neutralized
before using them for industrial or agricultural purposes. This review evaluates the …

Experimental sediment cores from Lake Ainsworth, Australia, were exposed to an induced
46-day, anoxic/oxic cycle in the laboratory, mimicking the seasonal thermal stratification …

The Bayer process holds an exclusive status for alumina extraction, but a massive amount of
caustic “red mud” waste is generated. In this work, three oxalate reagents: potassium …
