Recovery of sodium from bauxite residue by pressure filtration and cake washing
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 ...
Reduction of the width of particle size distribution to improve pressure filtration properties of slurries
The filtration properties of mineral slurries depend for instance on the properties of the solid particles and on the way how these particles arrange themselves when the filter cake is formed. In cake filtration applications, ...
Improvement of the filtration characteristics of calcite slurry by hydrocyclone classification
(Elsevier Ltd., 2018-09-01)
Hydrocyclones are used in the classification of solids for instance in the mining and minerals processing industries for modifying the particle size distribution of solids, as well as for ore concentration purposes. ...
Local properties of filter cakes formed from pH-adjusted bauxite residue slurries
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 ...
