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 ...
Prediction of pressure filtration characteristics of CaCO3 suspensions ground in a vertical stirred media mill
Cake filtration is an important unit operation in the processing of minerals and pigments. The filtration characteristics are strongly dependent on the upstream processing of the ore, such as grinding parameters. This study ...
Dissolution of sodium, aluminum and caustic compounds from bauxite residues
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 ...
Wet grinding of CaCO3 with a stirred media mill: Influence of obtained particle size distributions on pressure filtration properties
Chemical and process industries utilize stirred media mills for efficient fine grinding of solids. Stirred media mills, also referred to as stirred ball or stirred bead mills, generally have a good ability to produce fine ...
Enabling safe dry cake disposal of bauxite residue by deliquoring and washing with a membrane filter press
(SAGE Publications, 2015-02-16)
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 ...
