Meaning of FLOTATION PROCESS

 
Webster's 1913 Dictionary
 
 Definition: 
\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.
