OverviewHistoryIndustriesPrinciple of operationScience of flotationFlotation equipmentMechanics of flotationChemicals of flotation

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” Durin

Froth Flotation - an overview ScienceDirect Topics

Frothing agents are used so that the separated material is held on the surface as froth and can be removed. Froth-flotation is an extensively used separation technique, having a wide range of applications in the minerals processing industries and other industries. It can be used for particles in the size range from 50 to 400 μm.

Plastics flotation is a combination of froth flotation and gravity separation (Shen et al., 2001). Thus, the decrease of recovery with the increasing particles size is a consequence of the greater weight of the coarse particles, which require a larger number of air bubble carriers in order to float.
