Dissolution of sodium, aluminum and caustic compounds from bauxite residues
(Elsevier, 2015-08)
Bauxite residues consist of solid particles and a strongly alkaline liquid. Depending on the selected disposal method, the solids content of washed bauxite residues varies from 30 to 70 w-%. The objective of this study is ...
Recovery of sodium from bauxite residue by pressure filtration and cake washing
(Elsevier, 2015-08-10)
Bauxite residue, the main waste fraction of alumina production, is extremely hazardous to the environment, as well as to human health. After the recovery of the pregnant liquor, the washed and thickened bauxite residue is ...
Challenges related to solute analysis of bauxite residue filter cakes
(Elsevier, 2018-05)
Solute analysis of bauxite residue filter cakes is an important but not very well understood operation carried out at refineries and in scientific research. As more and more refineries rely currently on dry cake disposal ...
Local properties of filter cakes formed from pH-adjusted bauxite residue slurries
(Elsevier, 2018-04-03)
Solid-liquid separation of bauxite residue is a topical issue in the alumina industry, not least due to the great quantity and problematic properties of this highly alkaline residue. The objective of this contribution is ...
