Abstract
The use of a dialkylsulfosuccinic acid or salt thereof as a dewatering aid in the filtration of mineral concentrates provides reduced moisture content and substantial retention of the dewatering aid on the dewatered mineral concentrate when the alkyl groups of the dewatering aid contain 10 to 24 carbon atoms.
