Separation of plastic wastes using froth flotation – An …
Froth flotation is a complex process with many subprocesses, involving three phases: solids, aqueous medium, and air bubbles. The principle behind froth flotation is the attachment of the hydrophobic particles to air bubbles to be floated and recovered to the concentrate, while the hydrophilic particles are wetted by water and stay in the ...
