Beschreibung
Zusammenfassung:	Processes of thickening slurries such as from metal and non-metal based ore processes are disclosed. The processes include treating a feed slurry in a thickener apparatus with an indifferent salt in sufficient quantity to increase efficiency of solids-liquid separation as compared to a feed slurry in the thickener apparatus without the added indifferent salt. L'invention concerne des processus d'épaississement de suspensions tels que des processus de minerai à base de métal et de non-métal. Les processus comprennent le traitement d'une suspension d'alimentation dans un appareil épaississeur avec un sel indifférent en quantité suffisante pour augmenter l'efficacité de la séparation solide-liquide par comparaison avec une suspension d'alimentation dans l'appareil épaississeur sans ajout de sel indifférent ajouté.
