Zusammenfassung:	A process for treating and dewatering tailings comprising fine clay minerals, fine rock-forming minerals and water is provided, comprising treating the tailings with a sufficient amount of a collector to modify the surface properties of both the fine clays and rock-forming minerals; subjecting the treated tailings to froth flotation to form a fine clays and rock-forming minerals froth layer; and recovering the froth layer and subjecting it to dewatering.
