Beschreibung
Zusammenfassung:	The present invention is directed to a dewatering aid which functions unexpectedly efficiently in the dewatering of a particulate solid slurry, e.g. mineral ore concentrate or slurry, wherein a dewatering aid is added thereto followed by filtration of the slurry. Such improved dewatering results are achieved by adding to the mineral ore slurry, an effective amount of a dewatering aid comprising an alkoxylated C8-C11 alkanol or alkanoic acid wherein alkoxylation is conducted with propylene oxide or butylene oxide.
