Title
(EN) A METHOD OF STABILIZING SLURRIES
(FR) PROCEDE DE STABILISATION DES BOUES
Abstract
(EN)
This invention relates to processes for modifying the flow characteristics of slurries, particularly mineral slurries such as red mud from the Bayer process, using water-soluble polymeric emulsions to increase the slurries' angle of repose.
(FR)
La présente invention concerne des procédés de modification des caractéristiques de fluidité des boues, en l'occurrence des boues minérales telles que les boues rouges issues du procédé Bayer. Le procédé consiste à utiliser des émulsions polymères hydrosolubles accroissant l'angle de repos des boues.
