Handbook of Flotation Reagents ScienceDirect

Nowadays, they are used more and more in water treatment plants and also in waste treatment. Coagulants are chemicals that reduce the repellent charge on solids, allowing them to collide and agglomerate. In flotation of clay-containing ores, dispersants have been found to improve metallurgical results and reduce reagent consumptions.
