Froth flotation has been mostly examined to separate graphite as a hydrophobic part of the spent LIBs from the hydrophilic parts (mainly LiCoO 2). In the mineral processing plants (the main host of beneficiation processes), conventional flotation separation has been practically introduced for a limited size range (−25+150 µm).
