Challenges related to solute analysis of bauxite residue filter cakes
(Elsevier, 05 / 2018)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 ... -
Dissolution of sodium, aluminum and caustic compounds from bauxite residues
(Elsevier, 08 / 2015)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 ... -
Enabling safe dry cake disposal of bauxite residue by deliquoring and washing with a membrane filter press
(SAGE Publications, 16.02.2015)Dry cake disposal is the preferred technique for the disposal of bauxite residue, when considering environmental issues together with possible future utilisation of the solids. In order to perform dry cake disposal in an ... -
Local properties of filter cakes formed from pH-adjusted bauxite residue slurries
(Elsevier, 03.04.2018)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 ... -
Polyethylenimine-modified chitosan materials for the recovery of La(III) from leachates of bauxite residue
(Elsevier, 03.02.2020)The separation and recovery of rare earth elements (REEs) from leachates of bauxite residue has attracted increasing attention. Yet, the characteristics of bauxite residue leachates (low pH, low concentration of REEs, and ... -
Recovery of sodium from bauxite residue by pressure filtration and cake washing
(Elsevier, 10.08.2015)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 ...
