Flotation process

Flotation process\ A process of separating the substances contained in pulverized ore or the like by depositing the mixture on the surface of a flowing liquid, the substances that are quickly wet readily overcoming the surface tension of the liquid and sinking, the others flowing off in a film or slime on the surface, though, perhaps, having a greater specific gravity than those that sink.
