A process for dewatering mineral and coal concentrates which comprises mixing with an aqueous slurry of the mineral or coal concentrate a dewatering aid in an amount ranging from about 0.15 pound per ton to about 5.0 pounds per ton, said dewatering aid consisting essentially of an N-monosubstituted sulfosuccinamate of the general structure:
- ##STR7## wherein R is a linear or branched aliphatic radical having four to fifteen carbon atoms, inclusive, R' is a linear or branched aliphatic radical having four to fifteen carbon atoms, inclusive, and X is hydrogen or a sulfonate salt, there being one X as hydrogen and one X as a sulfonate salt, and thereafter dewatering the treated slurry by filtration.
